I've started working on this. I already have working tpop3d which uses=20
libevent.

Example, I've started about 1500 parallel connections to tpop3d server=20
(standard compilation from cvs head) and... it stopped serving after I gues=
s=20
1024 connections (FD_SETSIZE limit probably).

Connected to localhost.
Escape character is '^]'.
(no pop3 banner)

libevent version was tested with 1800 connections and it still accepted new=
=20
ones ( + properly displaying banner and serving things). libevent was using=
=20
epoll() here.
