Used to implement critical sections, etc.

This class has 3 methods : Lock, Unlock, and LocalUnlock. The only difference between the two last methods is that the last one never triggers SGI #8 (rescheduling signal, associated to KScheduler objects)

Lock / Unlock blocks are always used with the same object.

Lock / LocalUnlock are always used with the associated attribute of the timer/watchdog timer interrupt object.
