How do you see how much CPU is being used on the OLPC, while Csound is 
running in the Terminal?

The way to see if -B or -b will work or not is to see how much
CPU % your csound process is taking. If it is always at 100%, then
it will not do to just increase -B and -b, you will need to reduce the SR.

That's what I kinda figured. I've been playing around with -b and -B
and thought I just wasn't doing it right. It's never really worked.
Thought I'd give it another try, but reducing sr makes more sense to
me. That or get a higher-powered computer! :)
