The first message was on Python 3.6. On master, regrtest sees even more kinds of leaks: references, memory blocks and file descriptors. haypo@selma$ ./python -m test --match=test.test_multiprocessing_forkserver.WithProcessesTestBarrier.test_barrier --match=test.test_multiprocessing_forkserver.WithProcessesTestFinalize.test_finalize -R 3:3 test_multiprocessing_forkserver Run tests sequentially 0:00:00 load avg: 0.25 [1/1] test_multiprocessing_forkserver beginning 6 repetitions 123456 ...... test_multiprocessing_forkserver leaked [492, 492, 492] references, sum=1476 test_multiprocessing_forkserver leaked [221, 222, 225] memory blocks, sum=668 test_multiprocessing_forkserver leaked [4, 4, 4] file descriptors, sum=12 test_multiprocessing_forkserver failed 1 test failed: test_multiprocessing_forkserver Total duration: 5 sec Tests result: FAILURE |

Is it test_finalize or test_barrier? |

> Is it test_finalize or test_barrier? Try yourself: it only leaks when you run both :-) |
