right. the Roller object should probably be a singleton, but I was
talking more about calls to roller.getXXXManager(). I think those
methods could actually construct a new XXXManagerImpl instance to
return, rather than maintaining a reference to a single instance.
They could, but why create objects when you don't have to?
