Compare and contrast..

Spot the pattern? Exponential growth. not only that, but for the most
part, the build system is the same across all of these. If we continue
growing at the current rate without doing something about the build
process, we're all going to be needing 8-way Opterons with several
GB of memory to get any work done.

If kbuild2.5 is faster, and produces the same end result (or better
still, more accurate builds), there's no valid reason to ignore it
that I can see.
