IPowerThread.Close method

Releases the thread handle of this thread. Note that it does not stop a thread if it is still running; it simply releases the thread handle (i.e., the resources used to track the thread).

Thread handles should not be released until there is no further need to use other thread methods or properties. If a thread does not need to be monitored, its handle can be released immediately. The thread resources will be freed automatically when the thread terminates naturally.

THREADCOUNT continues to report a thread tally that will include threads whose handle has already been released. A thread ID value may not be used interchangeably with a thread handle value.
