I love the idea as a whole (if only because the detractors can be told
"Just use subinterpreters, then you get concurrency"), but this seems
like a tricky restriction. That means no subprocess.Popen, no shelling
out to other applications. And I don't know what of other restrictions
might limit any given program. Will it feel like subinterpreters are
"write your code according to these tight restrictions and it'll
work", or will it be more of "most programs will run in parallel just
fine, but there are a few things to be careful of"?
