I simpy stop MailScanner, put a lot of mail messages (2.000, generated
by postal)
in mqueue.in, then start MailScanner and watch when mqueue.in is empty.

'top' shows high system load (over 7) and CPU usage (roughly 75% user
and 25%
system). Memory used is always below memory available and no swap is
used.
It seems CPU bound to me.
