By default the -j argument is passed down to submakes, consequently
if you make submakes respect -j, then you negate the token-pool
because each submake will create its own pool.  QED: You're back
to where we started where "make -j 12" generates 65 jobs.

And that mechanism exists: remove the env var, give -j arg.

What we're talking about is how/if this should be used in "make
universe".
