Scratch most of the other questions, I've looked at some of the code and
realized some things.  Mainly that RTaudio isn't the problem, ChucK
itself is doing some /incredibly/ evil things in the audio callback.
(looping and checking a "finished processing" flag, and _sleeping_ for a
while if it's not?!!).  Running a race between the audio callback and
some other thread like this just can't happen, it will need to be
changed for any sort of decent realtime performance.

This is the one I need to know:

I think this is going to be a lot more work than I thought at first :(
