> Derby has a configuration property named {{derby.system.durability}} that disables I/O synchronization calls for many writes.  This sacrifices durability but can result in large performance gains, which is appropriate for tests.
> We should enable this in our test system properties in order to speed up the Hive compatibility tests.  I saw 2-3x speedups locally with this change.
