[chuck-dev] --bufsize under windows XP

Windows XP users (again):

On our XP systems (ever since there have been real-time audio 
problems when setting --bufsize to 1024 or greater.  Can anyone else 
confirm this?  To test this:

   > chuck --bufsize1024 foo.ck
   (where foo.ck is something that sounds fine with --bufsize256 or 512)

What about bigger buffer sizes?

We noticed this was causing audio interruptions in, after we 
switched to RtAudio 3.2.0.  Under XP, this allowed much lower buffer 
sizes and hence better lantencies, but it seemed to disfavor buffer sizes 
greater or equal to 1024.  It could be ChucK doing something dumb in 
interfacing with RtAudio, but it's weird this only happens for bufsize
>= 1024 on XP...  Thoughts?
