- It wasn't worth the complexity. It was only useful when running the
python profile tool, which executes python scripts. But that tool
isn't very useful when run against normal scripts. It has been
removed too.
- The sandbox also wasn't working inside snaps, appimages,
systemd-nspawn or chroots.
- Now using python3.4 on debian, and python3.5 elsewhere.
- Added test-distributions script that checks that
install-dependencies works on different distributions.
