Some of the refactoring you've done here seems likely to break things,
because you're basically making the relation locking happen later than
it does not, and that's going to cause problems.
get_object_address_relobject() is a particularly egregious
rearrangement. It seems to me that the right formula is to call
relation_openrv() if missing_ok is false, and try_relation_openrv() if
missing_ok is true. But that's sort of a pain, so I propose to first
apply the attached patch, which gets rid of try_relation_openrv() and
try_heap_openrv() and instead adds a missing_ok argument to
relation_openrv() and heap_openrv(). If we do this, then the
missing_ok argument can just be passed through all the way down.

Thoughts? Comments? Objections?
