Comment:

 (In [19511]) Fixes #5481. There is in fact no deadlock, whoever wrote this
 code was very careful to only issue wakes and waits so that a
 predicative/counter was not needed. However, there was a missing
 threadPoolCond.wakeXXX() call causing an uneccesary 10 ms delay in
 handling some requests, and just to avoid a small change mucking up the
 careful orchestration I've changed the wakeOne() calls to wakeAll() calls
 which are a little more robust (however they are NOT needed for the
 current code -- it's just to protect against possible changes in Qt
 customEvent() handling causing problems in the future.)
