which is the only situation under which add_oid_to_usage doesn't just
return its first parameter, it'll immediately crash on the next invocation
with a NULL pointer dereference.

I'm not sure it's worth all the trouble in an out of memory situation.
Perhaps just remove the return value and let the caller crash.
