Hey @clin1234! Thanks for working on this. I'm not the maintainer here, but I'm leaving a couple of comments to help move this forward.

According to #613 (comment), sharing Packer objects wouldn't be supported under free-threading, so this test is probably not needed. Could we run the test suite with pytest-run-parallel instead?

Whatever works: I borrowed this test from another fork, and I'm still learning how to modernize existing pytest tests to use pytest-run-parallel
