A failsafe control system for a valve electromagnetically driven for opening and closing an intake port or exhaust port of an internal combustion engine is provided. The valve is of the type which is held in a neural position, i.e., in a partly open position when an electromagnetic actuator is not energized. When the valve fails in opening, the supply current is increased than that at normal times to drive the valve to close, whereby to prevent misfire, backfire and a bad influence to intake conditions of other cylinders and thereby attain an elongated service life of engine parts. A failsafe control method is also provided.

The method of claim 3, further including the steps of: receiving a request from the master resource object to downgrade the second lock; and in response to receiving said message, causing said shadow resource object to downgrade the second lock. 9. The method of claim 1, wherein said shadow resource object performs the step of determining. 10. A computer-readable medium carrying one or more sequences of instructions for allocating a resource in a system that includes a plurality of first processes executing on a plurality of nodes, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of: causing a first process to obtain, prior to accessing the resource in a particular way, a first lock that grants permission for the first process t
