As I noted before this will present /etc/passwd as `executable'.
Adding a `test -x' will _not_ suffice, because `test' invokes access(2)
to test executability, and the answers this system call gives _cannot_
be trusted if the real uid is 0 or if it differs from the effective uid.

How does Perl implement `-x', Tom?
