--------------------------------------------------------------------
This seems to shave anywhere between 1 and 4 minutes off of pig-test. At it's
fastest pig-test is 4 minutes 30 seconds so worth the one line IMO. We also
benefit down the road if any other unit tests end up needing to get seed data.

> We don't need secure random numbers (for unit tests) so waiting for entropy
> doesn't make much sense. Luckily Java makes it easy to point to /dev/urandom
> for entropy. It also transparently handles it correctly on Windows.
