Implement a (timing) test case for wq sort.
Explicitly start promise prior to waiting for it.
Use global constant for sort size and tweak to 1GB of ram.
Write C++11 constructor in wq_run_lock code.
Allow combined workq promises to specify workq job flags.
Use combiner workq flags to make sort parallel.
More readable output flush, use less memory so my test machine won't swap itself to death.
