To be more accurate, when old_resource is disposed of it will dispose of any
remaining underlying new_resource objects, leaving a load of invalid
new_resource's which will then be free'd later - unsuccessfully.
So I either need to preserve the life of the underlying old_resource until
all visible new_resources are finished, or find some way to mark the
remaining new_resources as invalid.
