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

Example, I've started about 1500 parallel connections to tpop3d server 
(standard compilation from cvs head) and... it stopped serving after I guess 
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 
ones ( + properly displaying banner and serving things). libevent was using 
epoll() here.

ps. here is proof that it works, not usable for anything else (yet)
