[$] A Gilectomy update

In a rather short session at the 2018 Python Language Summit, LarryHastings updated attendees on the status of his Gilectomy project. The aim of that effort isto remove the global interpreter lock (GIL) from CPython. Since his status report at last year's summit, littlehas happened, which is part of why the session was so short. He hasn'tgiven up on the overall idea, but it needs a new approach.
