GNUS is telling me...

     323411774: INBOX

When I try to look in INBOX, GNUS consumes all available memory.  There
should be maybe a couple hundred unread emails, tops.

I'm using a local dovecot imap server.  Thunderbird seems to work OK
when I point it at my local dovecot.

Other groups served up by this same dovecot instance appear to be OK.
It's just INBOX that has this problem.

Thanks for your help!
