My Secret:
I may or may not know the exact way to release the GIL on python 3.10+
I might also know how to recreate this minimally and easily without C extensions
It's not a magic trick, or some weird off beat code that doesn't work.
It functional, typed, code. What it really is I'll never actually reveal directly. Because I already did by releasing TokenGate, the abstraction itself is simple readable and traceable in that codebase. (Once you see it, you know why.)
When I first unlocked the GIL I tested it and traced the exact requirements. You can do it with or without serialization (serializing makes it easier for obvious reasons once you know but the physics doesn't change). Threading can output ~45x operations across 32 workers on my system in varied normal task distributions. Take a look at these results:

Wave 14 + 15, Massive overload and still holding GIL free status.
TOTAL 131,068 131,068 0 89.091s
Avg latency : 0.386 ms/token
Peak overlap: 44.86×
All tokens submitted instantly per-batch.
I'll just say this: There are domains, there is physics, the CPU must obey these. So think about that and read TokenGate.
(Bonus hint: There is exactly 3 components required to unlock the GIL.)
