+1 for me also.

I also mentioned in some other thread the problem of suspending a laptop
with a local connection to an IMAP server (I use dovecot, but I guess it
isn't specific to the server on the end). Sometimes the connection will
live on, sometimes it will hang, sometimes it will silently fail and not
show any new messages.

I'm not sure if there's a right way for gnus to react to this sort of
things. Maybe it could listen via dbus to system events such as "link
has gone down/up"? NetworkManager does send some stuff, but I'm not sure
if there's a standard for this.
