Warming up in case of a cache failure would indeed be nice, we have had
a few troubles with cache misses for nova-consoleauth and shared
keystoneclient token caches (mainly nova) in the past when a memcache
node failed and came back online. Nothing serious, but somewhat annoying :-)

Thanks for the example config, it's a good starting point (especially
for an McRouter newbie like myself).

All the best,
