Wow! A lot of overhead in the debug build.  I checked the 
computed values are the same.  This is on my laptop corei5.

dub -b release-nobounds --force
parallel time msec:448
non_parallel msec:767

dub -b debug --force
parallel time msec:2465
non_parallel msec:4962

on my corei7 desktop, the release-no bounds
parallel time msec:161
non_parallel msec:571
