Comment (by jdemeyer):
Replying to [comment:9 vbraun]:
> I'm against including a function that is unsafe by default, thats just
asking for trouble. `test_executable` either has to `chdir` to ensure that
the user did not forget it, or refuse to run if `cwd` is writeable by
anybody but the user.
The insecurity is not because of `test_executable`, but because of Python.
So such a check should be added in `spkg/bin/sage` before running `sage-
run`.
