So that uses the memcache-client gem?  I seem to remember that (and
dalli) only connects when it's needed, but I suppose some apps use
memcached at load time.

The following should work, not the most elegant:

  before_fork do |server,worker|
    ObjectSpace.each_object(MemCache) { |mc| mc.reset }

An after_fork would probably send unnecessary messages to the memcached

Hopefully somebody else knows a more elegant way to handle this.
