Title:
  memcache client race

Status in OpenStack Identity (Keystone):
  New
Status in OpenStack Compute (Nova):
  New

Bug description:
  Nova uses thread-unsafe memcache client objects in multiple threads.
  For instance, nova-api's metadata WSGI server uses the same
  nova.api.metadata.handler.MetadataRequestHandler._cache object for
  every request. A memcache client object is thread unsafe because it
  has a single open socket connection to memcached. Thus the multiple
  threads will read from & write to the same socket fd.

  Keystoneclient has the same bug. See https://bugs.launchpad.net
  /python-keystoneclient/+bug/1289074 for a patch to fix the problem.
