Fwiw, a "light" version would have to run until some criteria was
reached to be sure we exercised enough code paths; that would be
something like mem exhaustion in this case. Certainly needs to be sure
that at least a few RCU grace periods have elapsed after that point,
i.e. that we have started our handling the deferred frees.
