So backporting the patches is probably best. However, what's the longterm strategy around this as its been a program for several years on more bleeding edge distributions i.e. Arch? Even when were talking mainline its a problem with Arch sometimes.

I would prefer not to have to use a backwards supported penv for Yocto alone. Does anyone have any experience with working on Arch and how to avoid these issues without either dealing with penv or yay for getting a older version of python, pre 3.12 I believe. > > There’s a number of fixes for the 3.14 changes to multiprocessing in git, so you likely need to backport those.
