"No. We're not changing the CPython implementation much. Getting rid
of the GIL would be a massive rewrite of the interpreter because all
the internal data structures (and the reference counting operations)
would have to be made thread-safe. This was tried once before (in the
late '90s by Greg Stein) and the resulting interpreter ran twice as
slow."

How much faster/slower would Greg Stein's code be on today's
processors versus CPython running on the processors of the late
1990's? And if you decide to answer, please add a true/false response
to this statement - "CPython in the late 1990's ran too slow".
