Possibly unrelated, but I suspect there's a bunch of weirdness lurking in there.
I often end up building lots of kernels (especially during a bisect), and
I've noticed that if I do a 'git bisect good/bad' and then do
make modconfig; make -j4 it will in fact do 4 streams.
But if I just say 'make -j4' and it decides it needs to do a modconfig,
it will then apparently lose the -j4 somewhere and run just one stream.
(But if it doesn't do a modconfig, the -j4 works...)
