It's worth noting one of @kazuho's earlier comments raises a race condition that still appears possible here:

Request A or Control:  PRIORITY( A -> B )
Request B:  PRIORITY( B -> A )
Control:  PRIORITY( A -> C )

These two initial frames race on parallel streams.  Which is the child of the other?  When A becomes a child of C, does B come with it?
