Pigeon is a communication system for LANs and uses a clients-server
architecture.

2) Bug
======
A login field longer than 8180 chars sent to the port 3103 causes the
immediate freeze of the Pigeon server that enters in an infinite loop,
so CPU raises at 100% and is impossible to login and to send/receive
messages.
