 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.

 P.S. I didn't try the same test using pthread, so it is a good idea to
 test (and fix if needed) pthread implementation as well.
