It seems like test__xxsubinterpreters still has race conditions.

See also bpo-37224 and bpo-33356.

AMD64 FreeBSD CURRENT Shared 3.x:

FAIL: test_subinterpreter (test.test__xxsubinterpreters.IsRunningTests)
Traceback (most recent call last):
  File "/usr/home/buildbot/python/3.x.koobs-freebsd-current/build/Lib/test/", line 492, in test_subinterpreter
AssertionError: False is not true

Later, when test__xxsubinterpreters is re-run in verbose mode:

FAIL: test_still_running (test.test__xxsubinterpreters.DestroyTests)
Traceback (most recent call last):
  File "/usr/home/buildbot/python/3.x.koobs-freebsd-current/build/Lib/test/", line 765, in test_still_running
AssertionError: RuntimeError not raised
