Bad test on my part, apparently.
$ python
>>> import os

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 8] Exec format error
So a script with no shebang will fail when the shell calls exec(). If
that's so, then starting the executable script with an interpreter is
probably shell-defined. In other words, each shell might do something
different to run a script that has no shebang. Most probably do default
to trying itself as the interpreter first. Interesting.
