What I was thinking is that somebody created a new resowner, did
something, and then called LockReleaseCurrentOwner() (because no locks
are needed anymore), or LockReassignCurrentOwner() (say you want to
abort a subtransaction, but do *not* want the locks to be released).
Anyway, I slightly lean towards having wrappers, you strongly against,
so that makes it an easy call.
