My "tiny cpuset" idea doesn't so much eliminate bloat, as provide a
thin alternative, along side of the existing fat alternative.  So
far as kernel source goes, it would get bigger, not smaller, with now
two CONFIG choices for cpusets, fat or tiny.

The odds are, however, given that one of us has just promised not to
code this, and the other of us doesn't figure it's worth it, this
idea will not live long.  Someone would have to step up from the
embedded side with a coded version that saved a nice chunk of memory
(from their perspective) to get this off the ground, and no telling
whether even that would meet with a warm reception.
