Now I have a dynamically allocated structure and thread functions use a
global pointer to that structure. One thread usually modifies some members
in the global structure, e.g. some counters, while other threads just read
these counters.

I have several examples (from Toolkit, EDMI and EMEA DAP Library) of
multiple threads in a PM program and some of them use semaphores and some
don't. I'm not very familiar with semaphores, yet.

What would be the best way to test my program? Start as many resource
consuming processes as I can on my machine and wait until my program
crashes or are there any specific testing programs (I have Validator from
DevCon) ?
