Yeah. What I had been thinking about is that maybe it shouldn't be just
a one-element cache. At the moment though we have no performance data
to justify complicating matters (heck, not even any to prove we need a
cache at all...) It'd be smart to try to profile some realistic cases
before spending any time coding.
