BTW, we may also want to try and increase the proportion of those vars
which don't have a global default (i.e. look at which variables fall
into this camp and that can be changed without too much trouble).
Regarding benchmarking, you may also want to try `elisp-benchmarks` in
GNU ELPA (I suspect those benchmarks will not be very much influenced
by your patch, tho, so please try the "scroll xdisp.c" first).
