Yeah, maintaining two systems doesn't sound like a good idea.
However, this would be a big change. I'm not sure how we validate a
change of this magnitude. There are both correctness and performance
considerations. I saw there had been a few performance results on the
thread from Thomas that spawned this thread; but I guess we'd want to
do more research. One question is: how do you decide how many buffers
to use for each SLRU, and how many to leave available for regular
data?
