IMAP process hanging Emacs, or just failing

["James Harkins" <jamshark70@qq.com>]

I'm sending this from webmail, not wanderlust (as I would prefer), because at the moment, wanderlust's attempts to contact the IMAP server are doing nothing except causing Emacs to consume 100% CPU on one of the cores.

I've seen this happen many times before, usually when the connection has been idle and it's trying to open a new connection. Usually I can resolve the problem by doing M-t twice (forcibly kill the old connection, and open a new one).

Today, however, this didn't help. Neither did closing Emacs entirely, relaunching, and restarting wl.

First relaunch of Emacs: in the Folder buffer, updating folder statistics cause an infinite loop.

Second relaunch of Emacs: Folder buffer, the same operation stops abnormally with the message "Process IMAP is not running."

How do I even begin to troubleshoot this? I really don't want to have to go back to *shudder* Claws mail...
