Some example run times with PR build:
W20170405-143441 05bc_summaryallhash thor completed 2:22.961
W20170405-143251 05bc_summaryallhash thor completed 1:43.090
W20170405-143034 05bc_summaryallhash thor completed 2:08.976
W20170405-142844 05bc_summaryallhash thor completed 1:46.907

There's still some variance (NB: this is a pathological test), but overall it's 10-20x faster
