Opening as a draft. Build already works (locally) but there may be some performance regressions. Hopefully it'll show in CI.

Tests are not taking longer than usual, so I think this is good to go ?
@matthewturk , would you advise slapping noexcept on every nogil function anyway ?

I'm ok with this going in, but I don't have enough expertise in cython to comment on the question raised.

I would advise that, yeah. But it's probably not strictly necessary.

ok done. I'll merge this and follow-up PRs when tests pass. Thank you both !

actually, this is causing compilation errors in CI, so I've reverted this part of the patch. Let's just keep in mind that this change may be the first suspect in the event of performance regressions in the near future.
