While that did work. I do not have a good idea on how to do list
rotation on an RCU list. I can see that it must require a pair of
synchronize_rcu, and that spells disaster (at least for handling it
inline).

Another way might be to randomize the deadlines along each branch to the
tree... Except we don't have deadlines at this point and we can't so
freely change the priorities.

Hmm.
