Sending you a link out-of-band to the full output of "find" before the
files were deleted.

But yes, I think so. This was 27 tests against an Intel Atom 4-core to

Raspberry Swarm (sounds like a Prince album), so I'm shifting to those,
although I don't think that the file build-up was processing-power-related.
