The test run was stopped by me terminating the stuck processes on the buildbot worker itself. This happens approximately once a month or so.
As of late, its been stuck in test_concurrent_futures, but it can get stuck in any test that uses multiprocessing (the spawned pool never terminates).

The root issue will be solved by bpo-37531: ensure that regrtest kills a worker process if it takes longer than TIMEOUT seconds.
