New submission from STINNER Victor:
When regrtest is used with -jN, regrtest spawn child processes to run tests. If
a child crashs, regrtest master process immedialtely fails. It would prefer to
be able to continue to run following tests. It's not because a single test
crashed that all tests would crash.
Example of output when a crash occurs:
-----------------
(...)
0:02:45 [118/404/3] test_bytes crashed -- running: test_multiprocessing_spawn
(67 sec), test_io (54 sec), test_subprocess (76 sec)
