Because the Unix stuff was maintained by a developer at Loki, and he was 
much more detailed-oriented for plumbing issues like that...the lowlevel 
bits of the Windows code, maintained at Id, probably never changed as 
soon as they worked.

In Id's defense, they were focused on writing a game.   :)

Don't be surprised if you find subtle differences between platforms like 
this. Merging sources that are mostly identical (like the Winsock and 
BSD Sockets) is a really good idea.
