First parallel speedup.  Running "lvish1Fail" with 2E5 takes 1.6
seconds on my laptop and speeds up to 0.67 seconds.  Unfortunately,
it starts of 6 times slower than "naiveFail 2E5" which clocks in at
0.27 seconds.

That's ok, because of course lvish1 is just a starting point.  We haven't
yet taken advantage of saturation or shared information.
