---------------------------------------------------------------

When I measured this the difference between 0.95 and 0.94 (unpatched latest from branch) was
about 10%.
With this I measured about a 5% improvement in 0.94, so it would account for half of the improvement
(although the runtime variance in the runs is pretty high).

Would be nice if somebody else could do some measurements.
