It was a modified xargs and a modified cygwin to allow command line
lengths > 1M. I would think that the fact that you see noticeable
timing differences between 32768 -> 262144 would make that pretty clear
that xargs was actually using these.
An unmodified xargs would have given errors if I attempted to use a
larger limit - hence my request to be allowed to use larger sizes.
