[PATCH] fud.c : timeout in do_proxy_request

[Rob Siemborski]

I just tried to duplicate the setup on our murder locally, and had no
success (The proxy timed out appropriately).  Of course, our proxies are
on solaris...

I did see fud-client timeout before the server did when I couldn't resolve
the backend the server is on, but this isn't your problem if you are
hanging in recvfrom().
