I'm at a Sprint at PyCON, as are many of the people I think would be
best at answering these specific questions.   So it is not surprising
that they are not answering them now.  I, myself, am personally interested
in finding out how languages I have never looked at do these things,
because I expect it to influence how one gets rid of the GIL.  I was
hoping to have an insight as to how one could avoid going the route
of reimplementing fine grained locks everywhere, pervasively, all
through the codebase.  But all I am seeing now is more evidence that
this is impossible.
