What is claimed is: 1. A self-protecting barrier system for retarding fire comprising: a fire-retardant barrier having a water-permeable first fabric covering a substantial area; said first fabric having a surface and said fire-retardant barrier having at least 9 pockets per square foot, each pocket having a volumetric capacity of between about 0.03 cubic inches and about 17 cubic inches, wherein substantially all of said pockets contain superabsorbent polymer in the amount of between about 0.01 and about 2 grams unhydrated weight of superabsorbent polymer per cubic inch of said volumetric capacity of said pockets; and said first fabric is porous, hydrophilic and flammable. 2. A self-protecting barrier system according to claim 1, where said superabsorbent polymer upon hydration with water forming a substantially continuous matrix of hydrated superabsorbent polymer which substantially fills said volumetric capacity of said pockets. 3. A self-protecting barrier system according to claim 1, wherein said superabsorbent polymer is a polyacrylate or a polyacrylate derivative. 4. A self-protecting barrier system according to claim 1, wherein said superabsorbent polymer is polyacrylamide. 5. A self-protecting barrier system according to claim 1, wherein each one of said pockets when the superabsorbent polymer is unhydrated is between about 1 inch and about 5 inches long and between about ½ inch and about 5 inches wide. 6. A self-protecting barrier system according to claim 1, where each of said pockets holds between about 0.005 grams and about 3 grams unhydrated weight of said superabsorbent polymer. 7. A self-protecting barrier system according to claim 1 further comprising a second water-permeable fabric opposite said first fabric. 8. A self-protecting barrier system according to claim 1 further comprising a second water-permeable fabric opposite said first fabric, where said second fabric is porous, hydrophilic and flammable. 9. A self-protecting barrier system according to claim 1 further comprising a second fire-retardant barrier and means for fastening said fire-retardant barrier to said second fire-retardant barrier. 10. A self-protecting barrier system according to claim 1 further comprising a second fire-retardant barrier and fasteners for fastening said fire-retardant barrier to said second fire-retardant barrier. 11. A self-protecting barrier system according to claim 1 further comprising means for fastening said fire-retardant barrier to a building. 12. A self-protecting barrier system according to claim 1 further comprising fasteners for fastening said fire-retardant barrier to a building. 13. A method of retarding fire from burning an object, comprising the steps of: providing a plurality of self-protecting fire-retardant barriers, each having a first and a second fabric, said first and second fabrics having at least 9 pockets per square foot, each pocket having a volumetric capacity of between about 0.03 cubic inches and about 17 cubic inches, wherein substantially all of said pockets contain between about 0.01 and about 2 grams of superabsorbent polymer per cubic inch of said volumetric capacity of said pockets, and wherein said first fabric is water permeable, porous, hydrophilic and flammable; covering substantially all of said object with said plurality of self-protecting fire-retardant barriers; and hydrating said superabsorbent polymer in each one of said plurality of self-protecting fire-retardant barriers with a sufficient amount of water to expand said superabsorbent polymer to substantially fill said volumetric capacity with a substantially continuous matrix of hydrated superabsorbent polymer and push said pockets out to tautness. 14. A method according to claim 13, further comprising the step of fastening said plurality of self-protecting fire-retardant barriers together for covering substantially all of said object. 15. A method according to claim 13, further comprising the step of evaporating or boiling a portion of said water of said substantially continuous matrix of hydrated superabsorbent polymer at a temperature of about 100° C. to form a steam layer at a surface of said first fabric for protecting said barriers from a fire. 16. A method according to claim 13, further comprising the step of quenching fire with said steam layer. 17. A method of isolating fuel from the flames of a fire, comprising the steps of: providing at least one self-protecting fire-retardant barrier between said fuel and said flames, said barrier having a first surface facing and exposed to said flames formed of a water-permeable, porous, hydrophilic and flammable first fabric and a second surface opposite said first surface formed of a second fabric, said first and second fabrics having at least 9 pockets per square foot, each pocket having a volumetric capacity of between about 0.03 cubic inches and about 17 cubic inches, wherein substantially all of said pockets contain a substantially continuous matrix of water and hydrated superabsorbent polymer in the amount of between about 0.01 and about 2 grams unhydrated weight of superabsorbent polymer per cubic inch of said volumetric capacity of said pockets, said superabsorbent polymer being hydrated with said water; volatilizing a portion of said water at a temperature of about 100° C. to form a steam layer at said first surface of said barrier; and deterring ignition of said fabric and preventing said flames from reaching said fuel by substantially extinguishing said flames with said steam layer. 18. A method according to claim 17, where said second fabric is water-permeable, porous, hydrophilic and flammable, further including the step of forming a second steam layer at said second surface of said barrier. 19. A method according to claim 17, further including the steps of dissipating said steam layer, and then removing said barrier.
