New submission from Ivan Levkivskyi:
This command:
./python -c 'import runpy, typing; runpy.run_module("test")' -R 5:5
test_collections
Sometimes gives spurious failures like this:
test_collections leaked [0, 0, 3, -3, 3] memory blocks, sum=3
I think this is because ABC caches of typing.ChainMap, typing.Counter, and
typing.DefaultDict are not cleared by refleak.py/dash_R_cleanup (presumably
because inspect.isabstract returns False on those)
Adding a manual clean-up of these cashes to cleanup_cashes() fixes the "leak".
