Hi Jeremy,

not sure to understand all ATM, but it gives an idea :

Would it be possible to run a system with a >=2.6.39 + threadirqs 
kernel, and all services
you like when don't make music, and then run a script to killall 
everything unrelated to music
and play ?

Please let us know where you put your great tips !

Thanks,
Fred
