Feature or enhancement

Proposal:

This suggestion arose from there not currently being a way in python to test for PyRefTracer_DESTROY events (that I could find), specifically from there not being a way to add a regression test for: #130382

Add some simple code to tracemalloc to count PyRefTracer_CREATE and PyRefTracer_DESTROY events.

tracemalloc.start()
tracemalloc.clear_traces()

i = []
del i

refs = tracemalloc.get_traced_refs()

print(refs)  # will print (1, 1)

tracemalloc.stop()

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
