 Replying to [ticket:7755 Andrey <nikolay@…>]:
 > Please see attached test. Code is very simple. It works when thread3
 uses thread3_func_workaround function and test is deadlocked when thread3
 uses thread3_func function. From the first view, it seems the problem in
 the shared_mutex::timed_lock function. Possible it have to signal
 "semaphores[unlock_sem]" semaphore when state.exclusive_waiting_blocked is
 changed from true to false. This action will wake up threads which are
 waiting for shared access.

 It seems your analysis were right. Please could you try the attached
 patch?
