    // rebuild() before invoking us.  Infos restored from the cache
    // are managed by the factory, and thus the known and already
    // deleted.  When infos are created via the factory's describe()
    // method, the factory must already exist and thus the infos are
    // automatically registered (and thus already deleted).  The
    // latter is because the factory must be in the same library as the
    // one invoking describe(), or one of its dependents; either way
    // since the factory is a global object, it has been constructed (the
    // query happens after global constructors).
    //
    // Which brings us back to the point: there cannot be infos we
    // care about at this point.  As we start, the derived factory has no
    // infos (guaranteed by derived rebuild()), so the only infos that
    // exist are those we create here below.
