dmatest: use pseudo random numbers

djbw · djbw · commit be9fa5a43641 · 2013-11-14T11:04:40.000-08:00
There is no need for dmatest to drain the entropy pool.

It would be nice to one day have repeatable runs, but would need a
larger rework to synchronize and order calls to the rng across test
threads.
