So, actually, it looks like there are a couple of methods related to 
UDP (sendUDPData / receiveUDPData) that does not run correctly. Michaël 
spent a lot of time trying to find this out.

BTW, the context is about ad hoc networks, service discovery, group 
multi-cast (IGMP based)...
We (Douai's team) will make an annoucement soon. So, keep reading 
squeak-dev ;-)
