Uggg. Well, IOCP can wait in an alterable state, but I tended to stay 
away from APC's.

That's fine. Well, IOCP works great for my needs. It been a while, but 
it "served" it's purpose, so to speak. And that's okay, for me. A bit 
selfish, indeed? ;^)

There is an older paper that talks about the 50,000 concurrent 
connection issue on the windozer. It was a great read, and taught me a 
lot. IOCP handles them fine. Humm, I wonder if I can find that sucker. 
Perhaps its on the waybackmachine...
