Test failures in parallel

export LIBMESH_RUN="mpiexec -np 2" is giving me 14 test failures. I believe all of them are the PressurePinning failing to find a point in the mesh. I tried one of the tests with Mesh/class=serial just to be sure and it still failed.

Damn. I tried libMesh all the back to f0def3fca and still saw this. Guess no git bisect from the libMesh side and going to have to do it the old fashioned way.
