I am sure you are correct. The whole Windows API is more multi-thread 
friendly than multi-process friendly, and operates far more efficiently 
that way, as I understand it. There is also some potential benefit on 
some *nix systems, where thread creation is far less costly than 
forking, or at least this used to be the case last time I looked at it.

Not that I like Windows all that much, but using it for a server is 
becoming more defensible as an option. As for portability, what *nix is 
there these days that doesn't have some sort of lightweight thread support?

Maybe the relevant parts of the system need to be abstracted out and 
threading generally made a build time option (on by default for Windows, 
off by default otherwise, maybe?)
