You probably don't want to do a full fork as it takes a lot of system
resources most of which you don't need.  Use a vfork and then have teh
child execute a execve system call.  The parent will suspend until you
issue the execve.

Caveats are that vfork doesn't make your code very portable from what I
glean from the linux kernel mailing list.

Um..hmm..lets see..you can probably find some good examples on the net for
this.
