Here is a very slapdash attempt at pushing the "chunk size iteration"
part of the tests down into the test executable, using null
separators. I think it's ugly, but maybe not quite as bad as I feared.
Unfortunately it only gives about a 4x speedup on my machine, and I
was hoping for much more. (We should really expect this entire thing
to run in a fraction of a second.)

Let me know if you think the tradeoff is worth it for now; I can
polish it up if so.

Thanks,
