Did you know about the `-P' option of GNU xargs? IIUC, it does quite the
same thing -- what does 'parallel' offer of that functionality?
Run up to max-procs processes at a time; the default is 1.
If max- procs is 0, xargs will run as many processes as
possible at a time. Use the -n option with -P; otherwise
chances are that only one exec will be done.
