Coincidentally, I've just been trying rc10 on Linux/FC5 both in daemon
mode where it behaved pretty well (a few issues unrelated to the above),
and in xinetd mode where it immediately displayed various of peculiar
behaviours on call set-up.  (I wasn't even attempting any "CR-slamming".)

I haven't had the chance to investigate, or even properly record, this
xinetd aspect.  And local priority juggling means, sadly, that I probably
won't be able to pursue it any time soon.  But just to let you know you
are not alone.  Count this merely as a "+1" for observing significantly
poorer behaviour under "xinetd".

But I also note and respect the author's:
   http://wiki.dovecot.org/InetdInstall

which says right at the top:
   "Preferred way to run Dovecot is to just start the dovecot binary..."
