I believe this to be safe, as the main thing that LockRefPtr provides over RefPtr is safe copying from a shared LockRefPtr instance. I've inspected the uses of RefPtr<PhysicalPage> and it seems they're all guarded by external locking. Some of it is less obvious, but this is an area where we're making continuous headway.
