Public bug reported:
Although most frequently observed in the openstack-dashboard, neutron-
api and neutron-gateway charms, this affects all OpenStack charm amulet
tests which utilize a service restart check.
The test is to make a charm config change, then inspect the unit for
process start time, and compare that start time with file modification
time of the relevant config file. In some cases, that arbitrary sleep
results in the _get_proc_start_time checking for a service start time
before the service is started, yielding OSError: [Errno 2] No such file
or directory: '/proc/1242'.
