object but the best things to cache are the most expensive--those that
take the most time to generate--and the most-often used.
Now I'm really glad you brought MySQL into this because it reminded me
that MySQL has a database engine that might work very well as a
baseline, persistent object cache. I'm almost certain it would be
faster than core's file-based cache if it were well-written. I'm

enough places to make it core-worthy. (If this is a horrible idea I
hope Deaton chimes in right away.)
If somebody wanted to bang out a client I'd really like to lend an
eyeball or two, maybe even a hand, to see if it would be an
