Big +1 from me in concept.

I am not sure how to do the implementation best.  mod_cgid doesn't 
really 'fork' in the sense most programs do, its mostly just starting up 
a cgi process -- from an executable on the file system.

This seems drastically different from the requirements of a generic fork().

Any thoughts on how you would want to implement this in a generic manner 
for any call from anywhere for any module?
