Well, I can't speak for Windows (which, I gather from your posts over time you are an expert in), but for Linux, I believe you are going to find the scheduler manipulation is going to be more overhead than the signaling you choose. If you really only want a thread to get to a certain point, and then wait until it is told to continue, then you can use suspend/continue. The first thread can call pthread_suspend on itself, which will take it off the run queue (so it no longer takes any CPU). Then the second thread can use pthread_continue to 'signal' it to continue. Your only overhead will be manipulation of the queues in the scheduler, which will have to happen regardless of your mechanism.
