Three things aren't yet implemented, waking up processes which are sensitive to the event, triggering of events, and garbage collecting list objects which came from expression objects. The garbage collection aspect is problematic since there doesn't seem to be a correct way to implement it given the constraints in the spec, including the way that's implemented by Accellera. It's something that will need to be dealt with at some point, but in the interest of forward progress it's being ignored for now.
