I sent a patch that was similar a couple of weeks ago, that used a
workqueue to do the rebuild. It didn't quite work then since it wasn't
safe to call get_online_cpus() from a multi-threaded workqueue then,
but I believe there's been a patch since then that makes this safe.
And if not, we could always have a single-threaded workqueue that
wasn't bound to any particular CPU.
