The only case so far that attached an actual number disagrees with your
assertion. Surprisingly, it is quite reproducable for me. The only case
where the build system isn't enough to max out the CPU for me is during
linkage. Given that this is kind of the last task to do, no big surprise
and nothing a different build system could fix.
