      Every instance of QWindowsPipeWriter has its own thread to watch the completion of its I/O operation. Instead it should use QWinOverlappedIoNotifier.

      Also, ATM QWindowsPipeWriter is using overlapped I/O and then waits for the I/O result, turning the whole excercise into a synchronous I/O operation running in a thread.
      That just makes no sense.
