The new test leaks references:

https://buildbot.python.org/all/#/builders/563/builds/105

test_interpreters leaked [216, 216, 216] references, sum=648
test_interpreters leaked [84, 84, 84] memory blocks, sum=252

Use "./python -m test.bisect_cmd -R 3:3 test_interpreters" to find tests which leak. Example:

$ ./python -m test test_interpreters -R 3:3 -m test.test_interpreters.TestInterpreterDestroy.test_from_current
0:00:00 load avg: 0.82 Run tests sequentially
0:00:00 load avg: 0.82 [1/1] test_interpreters
beginning 6 repetitions
123456
......
test_interpreters leaked [36, 36, 36] references, sum=108
test_interpreters leaked [14, 14, 14] memory blocks, sum=42
test_interpreters failed
