I think my post was unclear, I'm saying keep the realtime thread 
hidden, just make sure any references are either duplicated 
somewhere reachable by the GC, or only give the real time thread 
malloced memory.

Chances are almost all the memory the audio thread has references 
to will be referenced elsewhere anyway. And those that arnt, say 
a message object passed through a queue, just use malloced memory.
