The left over processes in the failing run are as follows:

26996 is the session leader, and who got the original kill signal. It looks like 27055 and 27060 never got the signal, or never logged it.

Title:
  services no long reliably stop in stable/kilo

Status in Cinder:
  New
Status in OpenStack Identity (Keystone):

Status in The Oslo library incubator:

Bug description:
  In attempting to upgrade the upgrade branch structure to support
  stable/kilo -> master in devstack gate, we found the project could no
  longer pass Grenade testing. The reason is because pkill -g is no
  longer reliably killing off the services:

  dsvm/0ad4a94/logs/grenade.sh.txt.gz#_2015-04-21_03_15_31_436

  It has been seen with keystone-all and cinder-api on this patch
  series:

  There were a number of changes to the oslo-incubator service.py code
  during kilo, it's unclear at this point which is the issue.
