DetachedStateManagers and ManagedCache

[William Dazey]

Hello,
I was looking around at the Broker implementation and I noticed that when
an entity becomes detached, the StateManager gets set to a
DetachedStateManager, but the StateManager in the ManagedCache still exists
and kind of bums around until the Broker is closed later. This seems to
make the ManagedCache get rather large if the Broker ends up staying open
for a long time and many entities managed. Am I missing something? Does the
ManagedCache get cleaned out some other way?
