threads: add function to calculate deadline for timed waits Usually, you have to call pthread_cond_timedwait() in a loop (because it can wake up sporadically). If this function is used by another higher level function, which uses a relative timeout, we actually have to reduce the timeout on each iteration - or, simpler, compute the "deadline" at the beginning of the function, and always pass the same absolute time to the waiting function. Might be unsafe if the system time is changed. On the other hand, this is a fundamental race condition with these APIs. 2014-01-31 18:50:56 +00:00			`struct timespec mpthread_get_deadline(double timeout);`

threads: add wrapper for initializing recursive mutexes Damn this overly verbose pthread API. 2014-01-31 18:50:25 +00:00			`int mpthread_mutex_init_recursive(pthread_mutex_t *mutex);`
