This is a great test because there's no signal processing. What happens 
here is:
     memory allocation and garbage collection (all but small integers go 
on the heap)
     occasional calls to oscheck() to check for interrupts
It's possible, depending on compilers and alignment, that XLISP cells 
are bigger on Debian.
It would be really helpful to profile the code. Also, it would be 
interesting to run the same in nyquist on both systems (not within 
audacity).
