/*
Bug in ECSocket code
- aMule-2.0.3:
amuled segfault
- aMule-CVS-20051127:
enter infinite loop error after the socket 10sec timeout
(ECSocket error: Invalid socket (uninitialized)).
webserver and amulecmd segfault with when you connect
to external port connection.
Amuled don't crash but seriously disturbed
Probably buggy on previous cvs version but not tested.
