ThreadCancel in Host::WillTerminate g_monitor_thread may be blocked on a call to pthread_cond_wait (for example, line 640). Now, by default, when a cancellation request is serviced g_monitor_thread will again own the mutex guarding the condition variable it was waiting on. This causes the call to SetValue in Host::WillTerminate to hit a deadlock. The call to SetValue does not appear to be needed, so removing it solves the issue. Patch from Stephen Wilson. llvm-svn: 109228
