No need to feel bad about it - there was simply no other way to do it: the BKL
basically represented all the single-CPU assumptions that were built into the kernel
from 0.10 up to 1.3 (and at least as much new BKL depending code going forward as
well ...).

Every last such piece of code had to be eliminated. So the BKL represented the
status quo - and eliminating the status quo is always hard, as the code that remains
became less and less important :-)
