Hi Chris. I do understand that you were talking primarily about OSX and not 
about Linux, and I'm not at all disupting the primary point you are making. 
But even though it may have nothing do do with your argument,  you made a 
statement about how "pd -rt" works on Linux (which I do have some experience 
with),  and I believe that what you said is in error. So, I felt that I 
needed to reply. The fact is, that on Linux, using POSIX real-time scheduling 
as enabled by the "-rt" option, _is_ different then simply "nice'ing" a 
process to a not so nice level. I just wanted to clarify that. That's really
