Btw, it's often worth using /usr/bin/time instead of the bash built-in time. Why? Because /usr/bin/time reports one absolutely _hugely_ important number (maybe more important than almost any of the other numbers in there). Which one? It's the "minor pagefaults". That's a very good approximation of memory usage overhead. We've already had one person report that they ran out of memory when packing. So memory usage is actually a problem. Anyway, it looks like the 16-byte window is the way to go, even regardless of any memory use issue.
