[issue26577] inspect.getclosurevars returns incorrect variable when using class member with the same name as other variable

New submission from Ryan Fox: If a variable 'x' exists in the global or local scope, and a function (also defined in the same scope as 'x', or lower) refers only to a member named 'x' of an object, inspect.getclosurevars will include a reference to the variable, rather than the member. Okay,

[issue26567] ResourceWarning: Use tracemalloc to display the traceback where an object was allocated when a ResourceWarning is emitted

STINNER Victor added the comment: I used this patch to identify a ResourceWarning in test_faulthandler when the test is interrupted by CTRL+c: it's really efficient! I will be very useful to identify all ResourceWarning that I saw in test_asyncio, like the ones seen on the AIX buildbot.
