This appears to be correct. In my defense, some of the MPI documentation examples don't free the results of an MPI_Comm_split either. In the offense, others of the MPI examples do free the MPI_Comm_split output, and I probably should have read through more than one example before writing the code. I'll put in a PR to fix it now.
