Does anyone allow unlimited or extremely large quotas?

Oh yeah - expunge on close.  God, that's awful.  2.4.x will fix that.
Switching filehandles to read-only won't help, because the standard
says to expunge on close!

If you actually WANT read-only, the command is called 'EXAMINE' by
the way.  It's like SELECT, but actually supposed to be read-only.

FYI - I've written an experimental "open the cyrus.index and cyrus.cache
files read only if the mailbox is opened with a read lock" patch.  It seems
to work fine, but I find that the index functions actually use a write lock
anyway because they could be updating \Recent data or \Seen data.  Oops.
So I'll have to fix that too.
