Subject: * In normaliseFState(), wrap registration of the output paths and the
   normal form in a single transaction to ensure that if we crash,   either
 everything is registered or nothing is.  This is for   recoverability:
 unregistered paths in the store can be deleted   arbitrarily, while
 registered paths can only be deleted by running   the garbage collector.
