* [3.6] bpo-31308: If multiprocessing's forkserver dies, launch it again when ↵Antoine Pitrou2017-11-031-5/+16
| | | | | | | | | | | | | | | | | | | | | | necessary (GH-3246) (#4252) * bpo-31308: If multiprocessing's forkserver dies, launch it again when necessary. * Fix test on Windows * Add NEWS entry * Adopt a different approach: ignore SIGINT and SIGTERM, as in semaphore tracker. * Fix comment * Make sure the test doesn't muck with process state * Also test previously-started processes * Update 2017-08-30-17-59-36.bpo-31308.KbexyC.rst * Avoid masking SIGTERM in forkserver. It's not necessary and causes a race condition in test_many_processes.. (cherry picked from commit fc6b348b12ad401cab0261b7b71a65c60a08c0a8)
