Here is a self-deemed "trivial example":

Have you thought about using threads?  This may not be what you want 
since you are looking at exec+fork, but they are certainly 
lightweight, and in my (limited) experience they are quite portable 
if you use a standard API, like POSIX threads.

For documentation, a good starting point is the glibc distribution.  
If you have a Red Hat-like system, read "/usr/doc/glibc-<version>
/README.threads" and check out the examples in "/usr/doc/glibc-<versi
on>/examples.threads".

There are even more thread tutorials out on the web than for fork(). 
 I found the following publication useful:

Good luck.
