The act of suspending the execution of one thread
and starting (or resuming) another. The suspended
thread is said to have been "preempted" by the new
thread. In QNX, whenever a lower-priority thread is
actively consuming the CPU, and a higher-priority
thread becomes READY, the lower-priority thread is
immediately preempted by the higher-priority thread.
