Naively, one might think that, if the code is rarely used, even if
it's inside the switch, it'll rarely be in the cache and thus wouldn't
make much difference.

But I suspect the cacheing issues are more subtle than just the total
amount of code in the switch statement, and the only way to be sure
is to measure.
