Going dangerously off-topic, but two points:

If you're using -j I've always gone under the impression you want the
value to be #cores+1, not #cores. That way you keep your machine working
full tilt.

But regardless, why not use "make -l" anyway? This way it's tied to
system load which is likely a more prudent method to decide whether or
not new make jobs are issued - e.g. if you happen to be running a make
process that is io-intensive, you likely want to run less of them, but
if you've got a couple jobs one of which is io intensive then some of
your cpu cores might be mostly idle... -l should allow you to max things
out better.

That said I've done precisely zero tests with this logic so all this
could be baloney :)
