I'm not sure whether I mentioned before, but this approach doesn't
work (at least on my RedHat Linux system) for scripts run with
parameters, e.g. lua -f. This is because the kernel seems to pass only
one argument to the program being run, so env gets "lua -f" and
complains that there's no such program.
