Reviving Gnus after suspend/hibernation

[ludo@gnu.org (Ludovic Courtès)]

Hello,

When Gnus is left plugged or has non-agentized nnimap groups, recovering
from suspend-to-RAM or hibernation has always been a problem for me:
sometimes Emacs is frozen upon resume, trying to get data from some IMAP
stream.

With Emacs 23, I would typically unfreeze it by running ‘killall
gnutls-cli’ (!).

With native GnuTLS support in Emacs 24, this is no longer possible, so
it goes like this:

--8<---------------cut here---------------start------------->8---
$ gdb $(type -P emacs) $(pidof emacs)

[...]

0x00007f2345838813 in __select_nocancel () from /nix/store/vxycd107wjbhcj720hzkw2px7s7kr724-glibc-2.12.2/lib/libc.so.6
(gdb) return (int)-1
Make selected stack frame return now? (y or n) y
#0  0x00000000004eed33 in xg_select ()
(gdb) quit
A debugging session is active.

        Inferior 1 [process 2204] will be detached.

Quit anyway? (y or n) y
Detaching from program: /nix/store/0p4r2m8pscisxj5crd65x34prdrrmkz4-user-environment/bin/emacs, process 2204
--8<---------------cut here---------------end--------------->8---

It works, but I tend to think that the ergonomics could be improved.
:-)

How do you people do?

Thanks,
Ludo’.
