Do you want to have an debate with Mark Crispin about correct behaviour of
IMAP clients? I still have the scars from last time, and that was probably
about 1997 :)

PINE sees that the messages in the selected mailbox have been expunged:
* 1 EXPUNGE
. OK Completed
It would need to do a 'LIST "" *' to spot that the list of available
mailboxes had changed.
I've just trying forcing this and it doesn't seem to unselect the deleted
mailbox. It is possible that it would sort itself out eventually, but the
deleted mailbox was still selected after several minutes.

Fair enough. I don't know whether this is actually a problem yet, I just
noticed a difference in behaviour from 2.3.X in my testing.
