hi guys, any updates on this issue?

[jorisgillis]

The pull request is still open. Still needs a review to be merged.

It would be nice to have this merged. For instance current state prevents usage of a python swagger code generated library in aws lambda (3.8 environment) where multiprocessing.Pool is not supported.

If anyone could make the merge it would be super nice ! I'm having issue with Pyodide and a python swagger code generated library.

I was trying to have a look on the issue but it's hard to find where the multithread initialisation hapend in the new version. Does anyone have a starting point ?
