Catalogs always consider resource data to be expired if not mid-transaction.

This way we'll cache when in a transaction, but otherwise always
hit the disk so the data is fresh.  This works because we
really only use resources mid-transaction, but it behaves correctly
if we happen to use a resource outside of a transaction.
