Is it not possible to do a mutex thread with the DSP function?  Would 
this assure that the DSP calls would have enough time to complete 
without fighting sys_pollgui() and the other calls for time?  Or 
would those have to be threaded as well?  It seems like when DSP is 
on that all other tasks need to be subservient to the computing of 
audio to ensure proper audio performance.

It would be really great to have some sort of solution to this within 
the Pd scheduler.
