Now that I've had some occasion to look around in bufmgr.c, I am very
unhappy that there are still boatloads of comments talking about a buffer
header's spinlock, when there is in fact no spinlock anymore. Please
expend some effort on making this less confusing for the next hacker.
Maybe make those comments talk about a "lock bit" instead?
