You end up calling CreateEvent() and CloseHandle() on every send.  I don't know
what the performance impact of doing that is, versus serializing the sends.
With serialized sends, in the best case, the send is issued immediately, which
works better if contention is rare.  Does anyone know what CreateEvent()
eventually turns into?

Also, does anyone know the send behavior for the management utilities, diags,
and opensm?
