> Oak degrades gracefully for observation listeners that can't keep up with the rate of
observation events fired. See {{BackgroundObserver#contentChanged}} for the gory details.

> As a side effect {{JackrabbitEvent#isExternal}} will always return {{true}} when this
degradation happens. However there is currently no way for clients to detect this and to thus
know whether the result of {{JackrabbitEvent#isExternal}} is reliable or not.
