Clearly performance benchmarking needs to be considered with this
change, but I expect it not to be a problem. (Or more accurately,
I expect that it may exacerbate problems with already-bloated data
structures, but I'm about to go on a data structure shrinking spree,
so by the time it comes up I sincerely hope it won't be a problem
anymore.)
