*should*? How is one correct and the other not? They are just
different behaviors. Ie. rake is the same as drake -j1.

The problem is that drake -j2 or more can royally screw a Rakefile not
written for it. Thus the "fix" is to remain backward compatible but
add a syntactical distinction for j-ready tasks. Then there is no
problem.
