tests take too long to complete on variant=debug

[Kojoley]

Typed b2 -j2 variant=debug threading=multi link=shared address-model=64 toolset=msvc-14.1 warnings=off libs/sort/test//test_parallel_stable_sort and it took about 5-7 minutes to complete (with variant=release it is done in seconds).

It does build with optimizations though:

Is there a target speed? Some issues will only occur in larger sorts.
