[New-bugs-announce] [issue36719] regrtest --findleaks should fail if an uncollectable object is found

[STINNER Victor]

New submission from STINNER Victor <vstinner at redhat.com>:

regrtest (python3 -m test) has a --findleaks option to log warning if the garbage collector finds uncollectable objects. Problem: regrtest only logs a warning, but exit with a success in that case.

Attached PR makes regrtest fail in that case and adds an unit test for --findleaks.
