Ahh.  Didn't know about 'access'.  Looks like I
could change

>>                os.path.isfile(filename) and
>>                is_executable(filename)):

into

             if (os.access(filename, os.X_OK) and
                 os.path.isfile(filename)):

because access returns false if the file/directory
doesn't exist.
