memcached configuration

[Jeremy Blain]

We run multiple daemons on the same machine using a similar setup.
Occasionally we have to flush a cache and having multiple daemons lets
us flush
one daemon, then the next a short bit later.
Flushing our entire cache at once would cause a fairly significant DB
load spike
on our DB servers.
