Sorry, but I take it back. We just can document that (1) "-j 0"
will give you some default, (2) we do not promise that the default
will be optimal for you from day one, (3) we reserve the right to
"improve" it over time, and (4) we promise that we won't make it an
insanely wrong value. And let's keep "0 currently means num_cpu",
which may or may not be optimal but it cannot be an "insanely wrong"
value.
