And your point is?
That the mutex is released if he closes the handle?

My point was he was creating 2 handles for every lock/release, and
never closing them. Won't take long to run out of handles.

In my final example I showed how to create/leak only one handle per
TCriticalSection object, no matter how many times it was used.
Acceptable for testing purposes, as a few leaked handles shouldn't
create it's own set of problems (like the run-away handles could).
For on-going usage, I'd make the handle part of the class and have the
destructor close it.

But then, I prefere to write in a non-deadlocking manner in the first
place.
