Running with CVS from 10.27.05 15:09 EDT and this patch, I get folder
corruption.  I can't easily reproduce it but it happens frequently (4 times
in 3 hours this morning).

The patch looks innocuous so I suspect CVS.  alpha4 doesn't have the
problem.  Is there anything in CVS which could have affected this?  I'll
update to the latest CVS and try some more.

I'm running 'dovecot --exec-mail imap' on Solaris with lock_method=fcntl;
the rest of the locking is default.

Of the four problems, the body of the message went missing twice.  And
twice the body of a message were overwritten by the headers of the next
message.  There's nothing surprising in the rawlogs or any other logs.
