Hi,

I noticed that for a few months, the Python test suite started to leak
more and more files /tmp. After a few weeks, a machine can have
between 2,000 and 50,000 temporary files created by Python. The
filenames are random, but I noticed the issue on buildbot worker
machines which only run Python. So I'm convinced that it's a Python
bug. Moreover, the files are owned by the buildbot user (which is used
to run the buildbot client and so all child processes).

I created an issue to investigate the root issue and try to design a
generic solution:
https://github.com/python/cpython/issues/93353

IMO the test suite should create a temporary directory per test worker
process and marks a test as failure if this temporary directory is
non-empty when the test completes.
