The hang usually happens at least once a day.  I've been checking mail much
less frequently this week (I'm at a conference) and it hasn't happened yet.
In the meantime, running with this patch (and the 'rawlog imap'
fix--thanks!)  I get these messages a lot (~1300 times a day):

imap(happy): Warning: cork changed, set=1, io=0
imap(happy): Warning: cork changed, set=0, io=0
imap(happy): Warning: buffer_flush=1, flush_pending=0

Does this tell us anything?  Or is this debug info only useful when there's
a hang?

Thanks!
