My multi-threaded server app is simulating "race conditions" - one of the
threads is firing before the other, when it mustn't.

My worker thread is responsible for pooling, queues, etc. and my
deallocation thread frees memory when the threads in the pool have
terminated (it does this by checking GetExitCodeThread). I've managed to
solve it by setting a flag for when the deallocation thread can free, though
this seems a bit prone to disaster. Especially since the worker threads
objects are derived from a base class and setting the flag is the classes
responsibility. I've read up on semaphores but can't quite figure out how to
implement them in code - maybe I'm being a bit stupid.

Ideas?
