This technique works only if the program being executed is invoked by
specifying a relative or absolute path for it.  If it is found by your
shell as specified by your $PATH variable, all bets are off ...

The whole point of John Gilmore's proposal was to address this problem
of executables being found by path-search and therefore having no
invocation-time knowledge of where they reside.
