I agree that this is not something that Popen should be doing. If you

I tried that and it didn't work, though not for this reason. I'm also
trying to read the output from the subprocess via a pipe and that wasn't
being collected for some reason. I didn't really track down why so far,
if it makes or

`Popen` is the wrong place to implement this functionality. It may be

In most shells $PWD is a magic variable that is maintained by the shell
itself.

by some shells. If subprocess were to set $PWD, os.setuid should set $UID,
and

I can see your point, though I think particularly in this case it's
(unfortunately) fairly common that scripts on POSIX platforms read $PWD
instead of finding the current working directory properly.
I'm probably not the first
