Well, you *could* have run() calls pull the "full on" code into the 
cache every time they're called, whether or not the code is actually 
executed. Obviously, you can do it with some of the data as well, but 
unless your effect is guaranteed CPU bound, you probably shouldn't do 
too much of that, or it'll be just about pointless to care about 
silence at all.


Anyway, this doesn't sound like something that belongs in XAP. If 
you're nervous, just have the host kill silent buffers (rather than 
turning effectively inaudible buffers into silent buffers), and all 
plugins will run full on all the time.
