Public bug reported:

While trying to change file injection to default off
(https://review.openstack.org/#/c/70239/) we observed nova-compute hang
[the log stops hard about 10 minutes before the test run finishes).
Thought to be a bug in the patch, we then reproduced this with the
config setting done purely in devstack, while trying to avoid the
kernel-hang with neutron isolated networks + file injection (not sure of
the number).

a trace of the hung process threads:
