Of course, the standalone runt ime should match the Audacity runtime, at 
least in this case, where there's no substantial interaction with 
anything outside of XLISP. So now we have 2 disparities to resolve. I 
think the next step is profiling under Debian to see where the time is 
going. I assume everything here is compiled for 32 bit architectures. 
There might be a big difference between running 64-bit vs 32-bit code 
(not to mention that Nyquist doesn't support 32 bit code -- but actually 
the latest version in SVN is running under 64-bit OS X and I'm in the 
process of testing others.)
