ok, this is much better than before :) i think this can be traced directly
to the mbox index being rebuilt and bindex (UI) not being notified. i'm 
curious about *why* this hapens though as this is one of those things
that should afect a lot of people. only reason for this to happen i can
think of is libmutt fastclosing and reopening the mailbox from under us.

print *message at this point ?

hum, could procmail be radically changing the maildir ? as in changing
the indexes ? or even touching dirs other than new/ ?

atm that's cosmetic iirc. important is bindex gets correctly updated. doesn't
it ?
