Better documentation seems required, but really the whole design seems
rather wacko. Backends must agree on numeric tranche IDs, but every
backend has its own copy of the tranche name? How do we even know what
agreement is? And every one has to "register" every tranche ID for
itself? Why in the world isn't registration done *once* and the tranche
name stored in shared memory?
