See above; I don't [think] mutexes and semaphores differ in this respect.

Actually, if you take the example of someone calling TerminateProcess()
against the process (or some other equally fatal
do-not-pass-the-finally-block abnormal exits), they will be different.

For semaphores, the handles will be mopped up, but the available count on
that semaphore will not be incremented.

Key information. Thanks.
