C-g doesn't work?  Then it's also a bug in Emacs, I've seen this with
XEmacs sometimes. (but you seem to be using Emacs)

Yup.  I also use a ssh tunnel for some of my mail (actually it's ssl
over ssh over a unstable telnet-proxy), but I'm not able to reproduce
this by just "kill -9 <sshpid>", Gnus try to re-open the server and
fail.  Can you reproduce why your ssh tunnel kills?  Does your emacs
hang if you "kill -9 <sshpid>"?
