> Long running sessions limit the efficient of revision gc as they keep
> reference to old node states.
> We should consider to add an MBean through which all sessions can be enforced
> to refresh. This would provide clients with means to fine tune revision gc by
> first calling that MBean and then triggering a gc cycle. IMO this is
> preferable to directly enforcing a refresh from the garbage collector. The
> latter is too invasive and also not required when there are no long running
> sessions. Offering this functionality to clients as an additional knob to
> turn is safer.
