As an alternative to the xargs-based approach for parallel processing
here, you should also look at GNU Parallel, which is very similar but
it orders its output as if you had run all the jobs in serial.

I've used it to implement map-reduce problems using pipes.  For
smaller jobs where the overhead of hadoop is too great, it works
really well.
