Main problem with this is forkatosis if there are too many files. Using xargs breaks the rm's up into fewer proc's and tends to run faster since the rm command can access top-level dir's a single time for authentication -- a big timesaver on networked file systems or ones with advanced security hacks.

You can also run xargs w/ multiple proc's, which allows the latency of one proc's to be used up on another (see the --max-proc option to gnu xargs for an example).
