Very fair question.  And, of course, packaging up WaitForMultipleObjects 
into select isn't going to be useful if it's not even the right API. 
With the current set of patches, which only support remote debugging, 
the only thing that shows up in the console input handle, for which you 
can use WaitForMultipleObjects.

To really implement select, with reasonable performance, I think you 
have to do actually spawn multiple threads, to use the appropriate way 
of waiting for different things.  My plan here was that when that 
situation arose we would have those threads signal an Event, which 
WaitForMultipleObjects can process.
