It seems it does, at least I haven't got any connection refused errors 
since I set client_limit to 1 on the imap and pop3 services.
BTW, the difference is about +10k open file handles, and 2-3 (judging 
from munin graphs, which aren't so precise) times "active" memory usage 
(this is on FreeBSD).
Are there any chances to solve this, or should I forget running in this 
mode until you implement async IO?
