I'm not sure I understand... popen() doesn't return a process object, it
returns a file handle.  Also, I don't see wait() or a process object in
the lua docs anyplace.  Is it part of an add-on module?  I don't think
there's any concept of process in ANSI-C, which is what the un-adorned
lua interpreter targets.
