Funny how blaming GIL for being a bottleneck is the least researched/not backed by performance measurement (before/after) part of the article. Everyone loves to hate GIL. maybe there should be T-shirts made for this for the C++ loving folks out there.

I looked into the GIL saturation as measured with gil_load (https://github.com/chrisjbillington/gil_load), but perhaps I should have included more numbers here.

To me, seeing the GIL held for 40% of time and significant time spent waiting on GIL by other threads was a fairly strong indicator. Keen to hear your thoughts/experience on it.
