It winds up stuck on a leftover process:
test_import (test.test_multiprocessing_fork._TestImportStar) ... ok
Warning -- Dangling processes: {<Process name='Process-199' pid=5220 parent=2709 started daemon>}
Which is likely related to one of the other numerous failure ERRORs further up in the log.
I'm preparing an IPv6-only buildbot
