Using "reliable" I mean, if no such fatal error condition as reveive "buffer 
full" (receiver too slow, receiver thread dead, ....) exists and "all is 
well", a UDP packet will not get lost.

I'm not able to specify this more precise because the definitions of 
"reliable" and "unreliable" in connection to TCP and UDP are not, too.
