> Inside Utilities::handleMmTableFinalPath, the cleanMmDirectories method is
> called sequentially for each element of the mmDirectory list, which might
> have a large number of elements depending on how many partitions were
> written. This current sequential execution could be improved by parallelising
> the clean up process.
