Probably not with fork(), but if you are running a fairly new version of 
linux (1.3.3x+, not sure), it has something similar called clone().  If 
given the right parameters, the child will have shared memory with it's 
parent.  According to the man page it doesn't work yet, but that's old, 
and supposedly it works fine.  I haven't tried it yet.
I've looked around on a couple of sun machines, but I couldn't find 
something similar, but I just looked real quick.
