Public bug reported:

When Keystone configured with memcached as backend and token storage
keystone didn't reuse connections to it and starting to fail after
having more than 500 connections to the memcached.

Steps to reproduce:

1. Configure keystone with memcached as backend.
2. Create moreless good load on keystone and watch for connections to memcached using netstat, ex. netstat -an |grep -c ":11211"

Expected behavior: 
connections number should be reasonable and be not more that the number of connections to the keystone (ideally :)

Observed bahavior:
Number of connections growing and seems than 
1. They didn't reused at all.
2. Lifetime of each connection is 600 seconds.
