But Comer and Stevens are a bit out of date these days... poll() is so
much more efficient (as UNIX networkers continue to tell me OVER AND
OVER AND OVER AGAIN), and lends itself much more readily to
object-based code. Unfortunately, we don't have it in Winsock, and
comparable models there are terribly complex and very badly
documented. Since I want my code to work in both instances, I either
need to abstract my network code out into a Windows and UNIX
conditional compilation model, or drop back down to select().

Agreed. Threads, IMHO, are supposed to do small and well-defined
things well so you can concentrate on the part of the code that's
doing big nebulous things badly. ;)
