#6 World Model stops responding to sockets

[Robert Moore]

The world model server stops responding to newly-connected sockets, and appears to have a large number of sockets stuck in the CLOSE_WAIT state. This may be caused by the socket-closing code.

Some ideas...

Basically:
1. shutdown socket
2. read to clear buffer
3. close socket

Should be fixed with commit 2a488502fbcbc9251c6f654cb2ed2476c190cc96
Needs to be tested against a busy server.
