(replying to myself to avert flames) OK, after reading the RCU docs, in all fairness there is a lot more to it than I described, in particular the database analogy is not quite valid because most of the hard parts are handled automagically by the DB. But, my point remains valid, RCU seems like too general a concept to be patentable, and would probably be obvious to many people on this list. Lee
