[PD] Pd 20% idle CPU usage on MBP

[brandon zeeb]

This thread comes up every year or two, try running Pd with JackOSX instead
of having Pd communicate directly with OS X.  You should see the Pd process
decrease it's CPU usage significantly.

My guess is it's a Pd-> PortAudio -> OS X thing.

Cheers,
