cristian: thanks thomas.

what I would really need to simulate 
(because I think there are some problems related to this at least in
the kernel/configuration that I am using):

- only _one_ socket
- bidirectional flow
- _multiple_ associations on the socket (udp style)
- _multiple_ threads/processes sending/receiving on the socket
(that is concurent access to the socket/associations both for
receives and for sends)

bye now!
