python38-fix-threading-v1.patch
At the outset: Thanks for the report and the detailed descriptions.
The threading issue with Python 3.8 (tested with 3.8.9 from the Ports tree) can
be reproduced via the script from comment #2. Following vanilla releases of
FreeBSD were tested:
- 11.4-RELEASE-p9 [amd64/i386]
- 12.2-RELEASE-p6 [amd64/i386]
- 13.0-RELEASE-p0 [amd64]
- 14.0-CURRENT main-n246037-ca6e1fa3ce8 [amd64]
If the attached patch is used, which contains the two backported commits, as
noted in comment #0 (BPO-19466 + BPO39511), the regression doesn't occur on any
platform listed above.
A side note: If a VM has only one vCPU, the threading issue doesn't seem to be
reproducible with an unpatched version of Python 3.8.9.
