 Much of it should be familiar to many contributors to comp.arch,
but certainly not everything will be familiar to everyone (if I
take myself as an example).  It also contains a little appendix
entitled "Advice to Hardware Designers", which is interesting.

The fun part about RCU is that the readers do not have to be dependent on the writers and vise versa. The readers can go full steam ahead, without giving a crap about what the writers are doing. However, this is useful in certain types of scenarios. It's not a silver bullet.
