This solution is called priority inheritance in real-time programming. A drawback of this solution is that the overhead of acquiring a mutex increases slightly, maybe 0.2 microseconds on a 100 -MHz Pentium, because the thread has to call os_thread_get_curr_id. This may +MHz Pentium, because the thread has to call pthread_self. This may be compared to 0.5 microsecond overhead for a mutex lock-unlock pair. Note that the thread cannot store the information in the resource , say mutex, itself, because competing threads could wipe out the information if it is |
