Neither mine ;-) I would definitly choose pthreads over clone() anyday if
I really need full threading. But using shared memory is better when
processes need to comunicate with each other, but most of the program
doesn't need it. 

About pthreads though, I would avoid that too if possible (if you want to
write portable programs) since different operating systems do different
things with pthreads and it is often hard to get working consistantly
between OS's.

Just my thoughts after using both pthreads and System V thingyies. 

Sorry for the getting it wrong again
