I've also always gotten everything to run with just xargs and minimal scripting. For my taste GNU parallel gets recommended a bit too quickly e.g. on Stackoverflow when the standard tools would do just fine. Your linked SO question is a prime example of that, xargs specific question yet there's a response that dismisses it entirely and suggests parallel when xargs can easily do the task at hand.
