I do it and it works fine for me. pthread_cond_signal is never going to block - it just releases one of however many threads are waiting on the condition variable (which, I imagine, is what you are trying to accomplish).
It may not block, but from your description it sounds like it causes an immediate context switch. A context switch is usually not nearly as bad as a block, but still ...
