[issue21963] 2.7.8 backport of Issue1856 (avoid daemon thread problems at shutdown) breaks ceph

[STINNER Victor]

STINNER Victor added the comment:

Does anyone have a *simple* script to reproduce the regression?

The changeset 7741d0dd66ca looks good to me, Python 3 does the same thing since Python 3.2 (the new GIL).

Anyway, daemon threads are evil :-( Expecting them to exit cleanly automatically is not good. Last time I tried to improve code to cleanup Python at exit in Python 3.4, I also had a regression (just before the release of Python 3.4.0): see the issue #21788.
