Grr. An argument for_not_ splitting.
It is indeed that way.
In http://lists.gnu.org/archive/html/bug-coreutils/2009-10/msg00179.html

And indeed in this case the decision would be a no-brainer. That is the
case for sort, for example.
Maybe we want a --parallel option (too bad -p is taken) for xargs that
forces the creation of the number of processes passed with -P or taken
from nproc (for example by starting "md5sum $1 $5 $9 ...", "md5sum $2 $6
$10 ...", etc.)?
That would be an interesting alternative to this core-count proposal...
