If /path/to/some/prog is startable (executable, parses, etc.), I
wouldn't expect any useful outcome in $results or $status. Essentially,
you're asking it to go into the background. If you want to wait around
for results, you'll have to drop the &. If you want to check back
later, that's outside the scope of this question; you'll have to write
/path/to/some/prog to report back by other means.
