The second part of my claim seems to have gotten lost.  In particular, 
*at present* the only handle is the console, so WaitForMultipleObjects 
works fine.  In future, there may be other handles; my plan was that for 
any handle for which WaitForMultipleObjects did not work directly, we 
would create an Event, and a thread that wait for the appropriate thing 
to happen and signal the Event.  Since WaitForMultipleObjects works with 
Events, that would still be the right primitive to actually detect what 
happened.

All that would need to change relative to the current code would be to 
create/destroy the threads as necessary.  So, the current implementation 
is only console-only in that some details haven't been added, not in 
that it's hardwired in some permanent way to consoles.

Does that seem like a workable plan to you?
