Fix rounding issue in run-jsc-stress-tests
Created attachment 439455 [details] Patch
Sometimes ceil(N/K) == ceil(N/(K-1)), plus Ruby Array.slice gives you a nil if the start offset is past the end. This fixes the crashes arising when you did hit that rare combination of N (number of tests) and K (number of parallel processes).
