[issue30758] test_pydoc hangs sometimes on 3.6 and master branches on ARMv7 Ubuntu 3.x

It seems like test_pydoc only hangs on ARMv7 Ubuntu 3.x. Why faulthandler doesn't dump a traceback? :-(

faulthandler is supposed to dump a traceback after 900 seconds. Here, regrtest was killed after 1200 seconds and test_pydoc was already running for 423 seconds.

./python  ./Tools/scripts/run_tests.py -j 1 -u all -W --slowest --fail-env-changed --timeout=900 -j2 -j8
