BTW, is there an official way to tell when the client closes the 
socket?  When  I'm reading data, I can tell.   If I'm not reading data, 
I can call the Get_Peer(socket) function and catch an exception.  It 
just seems there should be another way?

Thanks for all the advice I've gotten so far.  I'm 95% finished.
