add option for forcing map of pages by touching each one with a write at its begin, required as somehow behaviour changed, cache was experiencing page fault errors and handling by dsa is simply too slow

modification to qdp benchmark, returns to per-chunk barrier wait, uses userspace semaphore for one-way barrier from scan_b to aggr_j as scan_b should submit asap but aggr_j should wait on submission from scan_b, contains TODO for modifying code to support chunkcount not divisible by 2
