[chuck-dev] JACK correctness part IX (callback vs. blocking)

On the recommendation of Dave Robillard, Florian Schmidt, and other 
Linux audio developers, we have implemented callback functionality for 
real-time audio, while keeping the blocking functionality.  Both are 
accessible using command line flags (--callback vs. --blocking).  The 
default is callback.  Perhaps not surprisingly, this is much more 
stable for small buffersize on all platforms except windows 
directsound.  Hopefully, it is a step in the right direction for 
alleviating problems running chuck under Linux/JACK.

The newest version is in CVS:

     cvs -d :ext:anon-chuck at cvs.cs.princeton.edu:/cvs checkout chuck_dev
     password: (hit enter)

The code is in chuck_dev/v2/

I must admit that I don't know Jack and would like to ask Linux/Jack 
users here to give it a spin under various conditions.  Please let us 
know how things fare.  Dave, Florian, Leonard - can you guys give this 
a try?

Thank you very much!
