Ah, ok, thanks for describing the whole picture. Forget all I said
about the notify pipe and ignoring things - I was thinking of
Yes, this is somewhat of a problem.

This may help. Also, I don't recall a description of your dequeueing
thread(s), but if it could avoid the need to be notified on new queue
content, this problem would go away for you.

Yes, that would also help, at least to some extent. You could avoid
changing ACE code (and needing to remember to propagate your local
change) by constructing your own ACE_WFMO_Reactor_Notify object and
your own ACE_WFMO_Reactor object with your super-sized notify object.

You're welcome - good luck!
