n-body sorted-by "mem"

Always look at the source code.

(Lumpers and Splitters.)

Some of these programs are single-thread and some are multi-thread: compare "secs" and "cpu secs". Some of these programs are un-optimised and some are heavily optimised: sort-by "gz" source code size.

Some of these programs are "naked ffi" and some put that in a library. Some of these programs are high-level and some are hand-written vector instructions.

Always look at the source code.

	* possible hand-written vector instructions or "unsafe"
