Well, I made some minor changes to your proposal to avoid awkwardness,
so, in general, no.  The worst part was certainly the portability code
for wait4/waitpid/wait.

But any real awkwardness will be discovered by trying an
implementation for other operating systems.  Still, I don't expect
anything horrible, except for the fact that I have no way to test it
on any non-Unix systems.  (Actually, I might have a FreeDOS diskette
lying around somewhere....)
