New issue 2542: Not implemented: sandboxing for external function 'opendir' in
ubuntu 16.04
https://bitbucket.org/pypy/pypy/issues/2542/not-implemented-sandboxing-for-external
Timothy Watts:
In the process of updating my base image from 14.04 to 16.04 I noticed that the
sandbox is not quite working. It works in 14.04. I've been attempting to create
a `do_ll_os__ll_os_opendir` function and things like that but I feel like I'm
poking in the dark.
