------------------------------------------------------------
Thanks Mark for trying it out.
I analyzed last 60 Python Portable Precommit tests from Jenkins to see if I can
find some patterns. There was no obvious patterns, however, all tests submitted
to Jenkins agent12 failed. It's also more likely to fail if we parallel run
multiple Python Portable Precommit tests on the same agent, which means we may
be running multiple sdist parallel in this case(It's depending on test start
time, sdist running at first part, so if two test start time is close, they may
run sdist parallel.). However, even if we run only one Python Portable
Precommit test in an agent the failure still happens, so it's not enough to say
parallel running sdist caused this issue. However, it's still worth to check it
out.
I attached a list of these 60 tests in case it can help you any way.
