Detailed Description

A completion counter allows a single thread to monitor a number of ongoing concurrent activities for completion.

Each activity calls increment() on the completion counter when started, and decrement() when finished. The monitoring thread can call wait(), wait(nsec), or done() to determine the status of the concurrent activity. Only one thread is allowed to call any of the wait() functions; but multiple threads can call increment() or decrement(). The completion counter can not be destroyed until the last thread decrements the counter back down to zero.
