Also rather than running with 'make -j40' or whatever, it uses 'make -j1' but with 40 threads. This increases CPU utilisation quite substantially (almost 50%) - I think this was discussed some time ago,

MAKEALL supports this, but doesn't default to it, today. I'm wondering if we ought to make it the default for all non-single board builds. The winning point is right around boards-to-build == `grep -c processor /proc/cpuinfo` and I think is right around setting NBUILDS to that value, both on consumer multicore and heavy-duty 32/64 core boxes.
