Remove a deadlock condition. A bit of explanation is needed: When calling
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.
