By "the new branch isn't predictable", I mean that there's apparently
no way to guess which way it's going to go that's better than flipping
a coin.  If I could annotate the branch with the probability of the
branch being taken, my best guess would be "half the time".

OTOH, if I rearranged the code a little, the new test could become
highly predictable.  OK, I'll do that :-)

Thanks redirected to Evan, who worked hard for a long time on this. 
Thanks, Evan!
