2 points.
1) The original posting wasn't about find, it was about another pipe which
produced filenames on stdout, so comments on xargs were required.

2) find / -exec rm -f {} \; spawns rm everytime it encounters a file
so its very slow and expensive, whereas xargs collects all the filenames
together, bundles them up into lines which won't exceed the system limit
and then spawns one job for all of those. Its much more environmentally
friendly.
