We recently ran into this exact same issue. A solution along these
lines would be very useful to us as well. I am curious, though, is it
feasible to release all state related to a filesystem immediately when
it is unexported? It seems like that would be ideal from the
perspective of the administrator of the server, but perhaps there are
technical reasons why that isn't easy or even possible.
