That would not help, as it would count as one gbuild job. Either you
would allow only one binfilter job to to run, or you would end up
with the same problem as before, with two parameters ("max-jobs" and
"num-cpus").

Right.

Not really. It has enough directories to build halfway decent (as much
as possible in the old build system) all by it self.

No, as in gbuild no module waits for another. As long as there are
_any_ executable jobs in _any_ modules, CPUs will get saturated.

So:

- tail_build (in gbuild) -> maximum CPU saturation
- binfilter -> as good or bad as in the old build system

Best,

Bjoern
