Skip tests when there's no space left on device? #97642
Description
Right now buildbots sometimes fail with something like:
======================================================================
ERROR: test_zipfile (test.test_multiprocessing_main_handling.SpawnCmdLineTest.test_zipfile)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/buildbot/buildarea/3.x.pablogsal-arch-x86_64/build/Lib/test/test_multiprocessing_main_handling.py", line 223, in test_zipfile
with os_helper.temp_dir() as script_dir:
File "/buildbot/buildarea/3.x.pablogsal-arch-x86_64/build/Lib/contextlib.py", line 137, in __enter__
return next(self.gen)
^^^^^^^^^^^^^^

OSError: [Errno 28] No space left on device: '/tmp/tmpcuj5padp'
Log: https://buildbot.python.org/all/#/builders/484/builds/2129/steps/5/logs/stdio
The problem is that it creates some problems:
- It reports back to contributors: gh-91212: Fixed flickering when the tracer is turned off #95129 (comment) Some people might get confused by it, clearly
- It fails the CI, so it is now red:
We might catch OSError with error code 28 on linux and just skip tests.
How does this sound to others?
If this looks like a good idea, I will send a PR.
