After posting my first response to your post, I remembered that Donald
had provided a link to the commit that removed the -E. From a quick look at
that commit, ISTM that distil's approach to restarting is somewhat easier
to reason about and debug than the approach taken by pip to implement -E:
it takes place before any of the rest of the logic in the restarted program
is run, so a question like "why didn't restart_in_venv get called, when it
should have been?" doesn't arise. There are no rabbit-holes to go down. The
approach in that snippet could apply to any script - it's not especially
