I really don't care about "WSACleanup()"; that's just 
Windows-specific crap, as far as I'm concerned.  Presumably the right 
thing will happen when process eventually exits, and that's all I 
care about.

In each case, the calls to "exit()" should not be happening unless 
there is a serious error in your programming - i.e., they should 
never end up being called under normal circumstances.  If you want, 
you can change them to something else, but (once again) they should 
not ever get called in properly-written code.  You can think of them 
as a debugging aid.
