/* For the expunge bits we took a very cautionnary approach, meaning
we create a temporary mailbox in the tmpdir copy all the message not mark
deleted(Actually we copy all the message that may have been modified
i.e new header values set; UIDL or UID or etc ....
and skip the deleted ones, truncate the real mailbox to the desired size
and overwrite with the tmp mailbox. The approach to do everyting
in core is tempting but require
- to much memory, it is not rare nowadays to have 30 Megs mailbox,
- also there is danger for filesystems with quotas,
- if we run out of disk space everything is lost.
- or some program may not respect the advisory lock and decide to append
a new message while your expunging etc ...
The real downside to the approach is that when things go wrong
the temporary file may be left in /tmp, which is not all that bad
because at least, we have something to recuperate when failure. */
