Subject: skip random failing tests
Date: Thu, 18 Jan 2018 15:48:52 +0100
skip random failing tests:
in _test_multiprocessing.py:
test_async_timeout
test_waitfor_timeout
test_wait_integer
in test_events.py:
test_run_until_complete
test_signal_handling_args
test_call_later
Reported to fail on ppc64le host on multiple osc build trials:
(all failed for ppc64le, except one for ppc)
