Zane Bitter c9792b96d2 Create replacement resource atomically ...

Use a single transaction to create the replacement resource and set it as
the replaced_by link in the old resource. Also, ensure that no other
traversal has taken a lock on the old resource before we modify it.

If we end up bailing out and not creating a replacement or sending an RPC
message to check it, make sure we retrigger any new traversal.
