Title:
  Container updater may be stuck and not make progress

Status in OpenStack Object Storage (swift):
  Fix Released
Status in swift package in Ubuntu:
  New

Bug description:
  Container updater may be stuck and not make further progress. This was
  reported after the "PipeMutex" primitive was added to fix a deadlock
  in the logging layer. The bug can be reproduced with the attached
  python script.

  The observed behavior is that after some time the container stats are
  no longer updated and strace for the daemons shows that they are all
  stuck in "epoll_wait".
