What is claimed is: 1. A fluid ejection container system for containing fluid, comprising: a first chamber that contains the fluid and has associated therewith an air accumulation area; a second chamber having at least one fluid ejection port; a barrier separating the first chamber and the second chamber; at least one channel bypassing the barrier to allow communication between the first chamber and the second chamber; wherein the barrier is permeable to fluid but is not permeable to air when wetted with fluid. 2. A fluid ejection container system for containing fluid according to claim 1, further comprising: a third chamber having a capillary medium that contains the fluid; a passage between the first and third chambers communicating the fluid at a level wherein the passage is wetted with the fluid. 3. The fluid ejection container system according to claim 1, wherein the channel further comprises a flow limiting mechanism. 4. The fluid ejection container system according to claim 3, wherein the flow limiting mechanism allows communication from the third chamber into the first chamber. 5. The fluid ejection container system according to claim 3, wherein the flow limiting mechanism does not allow communication from the first chamber into the third chamber. 6. The fluid ejection container system according to claim 3, wherein the flow limiting mechanism allows one-way flow from the first chamber into the first chamber. 7. The fluid ejection container system according to claim 6, wherein the valve is a ball/spring valve. 8. The fluid ejection container system according to claim 3, wherein the flow limiting mechanism is a valve. 9. The fluid ejection container system according claim 8, wherein the valve is a check valve. 10. The fluid ejection container system according to claim 8, wherein the valve is a duck bill valve. 11. The fluid ejection container system according to claim 3, wherein the flow limiting mechanism is a filter material. 12. The fluid ejection container system according to claim 11, wherein the filter material is a membrane. 13. The fluid ejection container system according to claim 12, wherein the membrane is a fabric material. 14. The fluid ejection container system according to claim 3, wherein the flow-limiting mechanism is at least partially defined by a flow-limiting geometry. 15. The fluid ejection container system according to claim 1, wherein the air accumulation area includes an upper part of the first chamber. 16. The fluid ejection container system according to claim 1, wherein the air accumulation area is defined by an area of reduced cross-section provided above the first chamber. 17. The fluid ejection container system according to claim 16, further comprising a flow-limiting mechanism at least partially defined by a flow-limiting geometry of the reduced cross-section air accumulation area. 18. The fluid ejection container system according to claim 1, wherein the first chamber being evacuated to a negative gauge pressure when being filled with the fluid. 19. An ink jet printer comprising the fluid container system of claim 1, wherein the fluid is ink. 20. A fluid ejection cartridge comprising the fluid container system of claim 1 and a fluid ejection head. 21. An inkjet printer cartridge comprising the fluid container system of claim 1 and an inkjet printhead.
