If you do not want to "force" people to change their code, you will
probably need to offer a "stub" fork() to link against on non-MMU CPUs.

the majority of the time, it isnt just fork() that needs to change.  any
exit() in the child needs to be changed to _exit() too.

The sole purpose of vfork is to immediately invoke exec() Any other purpose is forbidden. In what case would an exit even be required?
