PUGH crashes if there are too few grid points to synchronize

PUGH crashes when there are not enough grid points while synchronizing. It apparently assumes that each process has at least as many grid points as there are ghost zones. This is easily violated with small, distributed grid arrays. The test case CactusTest/TestArrays/test/arrays0.par shows this failure when run on 2 or 4 processes.
