I was also going to fold this into the integration test arguments in a later
patch, since we have the same flags there. The integration tests are marked as
deprecated but I think we should keep them around as it's nice to have tests
that don't include the really heavy unit testing framework. It's the only way I
can do multi-threaded tests on the GPU.
