I fail to see what is wrong the simplest solution of all:
Just a spawn(program, argv, envp) call.  To change the childs
file handles, for example, you

a) switch your file handles around 
b) spawn the child
c) switch your file handle back

This is easy to do with dup() and dup2().  Other things
can be handled similarly..  

More complex uses of fork can be done better using multiple threads
(lightweight processes).  OS/2 for one uses this approach, and
it seems to be pretty easy to use, without the goofiness and
peformance problems of fork(), which can be considerable on
some architectures.
