bug#16026: Gnus shouldn't use old connections

[Stefan Monnier]

Package: Emacs
Version: 24.3.50


Gnus should consider a connection as dead if it has been idle for more
than some timeout value (e.g. 5 minutes).  This bites me every day when
I wake up my computer: if I just hit `g' to refresh the *Group* buffer,
it *always* hangs (I guess it would timeout but only after a long wait,
like 2h).  Instead, I have to go to *Server*, close each server, go back
to *Group* and then hit `g'.
