I think fixing the orphaned swap pages problem will eliminate the problem all together. Probably there is no need to optimize swapoff. Because as the system is shutting down all the processes will be killed and their pages in swap will be orphaned. If those pages were to be reaped in a timely manner there wouldn't be any work left for swapoff.
