Proposal: Taking over/up network maintainership

Hi Dan,

The long term goal is not to revamp the entire API of network, just the high-level interface in the Network module. Currently (actually, for the entire past, like, 5 years I've been using network), the documentation of the Network module has stated:

"This module is kept for backwards-compatibility. New users are encouraged to use Network.Socket instead.

Network was intended as a "higher-level" interface to networking facilities, and only supports TCP."

Why keep around a deprecated high-level interface and recommend people use the low level one. Seems much better (long-term) to overhaul the high-level interface in Network so that it actually becomes recommend over writing code using Network.Socket itself.

I've previously entertained the thought of taking up maintainership, but so far was held back by the fact that I don't do windows dev experience. I've discussed this in #ghc before and the consensus was that *nix only maintenance is probably still better than no maintenance.
