heh. I was just doing it the way Tom suggested - see attached. With a 
little more trouble we could also keep track if the listened for events 
and sometimes save ourselves a second call to WSAEventSelect, but I'm 
not sure it's worth it.

It all depends on the overhead of WSAEventSelect().  I'm sure your version would run faster, but I just don't know if "slower" would be measurable.

BTW:  I would suggest changing your comment to:

       /*
        * make sure we don't multiplex this kernel event object with a different socket
        * from a previous call
        */

Thanks for tackling this problem too.
