Well, that was stupid. Looks like I suck at Perl and couldn't write an
actually working script. I was looking at the low user/sys CPU usages,
but since they looked ok for some processes, I just thought that Dovecot
is so awesomely fast elsewhere too :) So the problem was that it
reported only the first process's values, which worked well for long
running processes but not for short lived processes..

Attached a new script. Here's another output of what I get myself:

type	real	user	sys	reclaims faults	swaps	bin	bout	signals	volcs	involcs	count
master	1252.14	0.58	2.70	138271	 0	0	0	16	0	30101	69	1

Most of this data is for running "rm -rf mdbox;imaptest secs=2" in a
loop and looks like imap-login was with service_count=1.
