To feel anything like the original the new getblk has to be idempotent: subsequent calls return the same block. Another issue: we need to be able to find the appropriate mapping for the getblk. That means either looking it up in yet another [major][minor] vector or changing the type of the argument to getblk, which is not as painful as it sounds because it isn't used in very many places any more. -- Daniel
