I don't know what is going on here.

So ... would importing and using the `signed_id` function from #14254 be
sufficient here?

I'm not sure why this isn't working.

This seems very familiar. I am pretty sure we have other platforms where
this happens - #10285 seems to have this, for instance. #8847 should have
fixed this a long time ago, but maybe I have the wrong stuff now?

No idea. Maybe a permissions thing?

Same issue as above, I would say.

Aside from the bizarre expected OSError, I would guess this is closely
related to the next one.

This seems to be from the command
{{{
sage: (out, err, ret) = test_executable(["sage", "--ipython"],
"\n3**33\n")
}}}
but when would IPython return negative 6?
