" *) Rework the WIN32 CV code to signal the condition only if one or
     more threads are blocked on the condition variable. If no threads
     are waiting on the condition variable, nothing happens. The change
     also eliminates the thundering-herd problem of the manual-reset
     event, which (theoretically) wakes up all threads waiting on. Now
     the behavior of the CV's should be the same on Unix and win32
     platforms. PR 42305.  [Davi Arnaut]
