I guess the symbols are a mosix thing, but it should still show some
sort of segmentation fault trace, no? maybe only the assembly opcode...
It seems that the SEGV is detected, rather then caught. This may also be
related to mosix - I'll check it with the mosix developer.

I added the parameter you suggested and appended the output. Modex seems
to be working because I use it to exchange the IP and PID, and as you
can see at the bottom these are received OK. I'll try debug printouts
specifically in add_procs. Thanks for the advice!
