It is, but this option is usually overkill and will significantly slow
things down, due to all the disk i/o involved in calculating an MD4
checksum for every file that has the same size.  Remember there is
already a whole-file checksum on the receiving end to make sure files
were transferred correctly.  One case where --checksum does make sense
is if you know you have files of the same size that change frequently
(which is the case with some db stores).
