Right. Compression should be used to save network bandwidth, but in
general, these days, files on disk should be uncompressed.

I'd rather not have more Windows-specific cruft in the socket and
select module source code -- they are bad enough already. Dynamically
loading winsock probably would mean that ever call into it has to be
coded differently, right?
