A PrioritySemaphore operates in the same way as a Semaphore. Its an owner-less Lockable object that is sensitive to priority.

Scheduling

Threads blocked on a PrioritySemaphore are resumed in priority order, highest priority first.

Error Checking

An attempt to increase a PrioritySemaphore beyond its maximum value will result in an InvalidOp_Exception.
