BTW, looking at the spec for pthread_cond_wait, there's actually no mention about a limitation regarding using pthread_cond_signal invoked from within a signal handler to unblock a pthread_cond_wait. However, this does not work either for me. If you follow the signal operation, I can see that when it reaches the nxsem_get_value() on the cond->sem, the semaphore value is zero and the sem_give is not done. Should this work? Best, Matia
