Keeping all CPUs busy

[Urs Thuermann <urs@isnogud.escape.de>]

I sometimes run many CPU-intensive processes in a loop like this

    for f in *; do lame -h $f ${f/wav/mp3}; done

However, this will run only one process at a time.  Executing all
processes in the background would execute them all at the same time.
Is there an easy way to run n processes at time, when you have n CPUs?

On could of course write an Makefile and run make -j2, but I'd like to
know I there is a simpler way without Makefile or something like that.
