Finalizing correctly when using MPI #852

In the MPI example, there is code like this:

# we need to close HDF5 and finalize the info object before finalizing MPI
finalize(info)
HDF5.API.h5_close()

MPI.Barrier(MPI.COMM_WORLD)

MPI.Finalize()

So is this required now for correct usage of HDF5 with MPI?
