First, its not a good idea to use invalidateAllObjects() to free

saveChanges() doesn't release snapshots, unfortunately, which I
would surmise is the problem.
But if snapshot reference counting is working as advertised,
dereferencing the only editing context containing references to the
snapshots should release them.
it may also be acceptable to use dispose(),
dispose() should be invoked when an editing context is about to be
garbage-collected, so sending an explicit dispose() message seems
redundant.
but invalidateAllObjects(), and its variants, are the only way to
flush the snapshots.
Other than removing any references which doesn't involve the
invalidateAllObjects() overhead of converting all of the objects to
faults. So invoking invalidateAllObjects() seems like a waste to me.
