Of course, to make things really interesting, we could have n files,
comprised of n-1 setuid/setgid scripts and 1 setuid/setgid binary, with
each script calling the next as its #! argument and the last calling the
binary. ;-)
The '#!' exec-hack does not work recursively. I just tried it under SunOs 4.1.3
It generated no diagnostics and exited with status 0, but it also didn't execute
the target binary.
I suppose that fact that it didn't barf with an ENOEXEC or similar error
qualifies as a bug.
