    Subject[PATCH] Releasing resources with children
    Releasing resources with children

    What does it mean to release a resource with children? Should the
    children become children of the released resource's parent? Should they
    be released too? Should we fail the release?

    I bet we have no callers who expect this right now, but with
    insert_resource() we may get some. At the point where someone hits this
    BUG we can figure out what semantics we want.
