[issue27535] Ignored ResourceWarning warnings leak memory in warnings registries

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

Alexander Mohr reported a memory leak in his code using botocore (Python client for Amazon S3): bpo-33565. His code emited ResourceWarning, but these warnings are ignored by default. The link between ignored warnings and a memory leak is non obvious.

Serhiy: what do you think of backporting my _warnings change for the ignore action?
