Yes, it is possible to fork off a new process that isn't a child of the 
main process. All children get killed, but if you split the recording 
process off, it won't be killed. I think were just dealing with 
semantics here (new thread versus new process). I'm not sure what the 
correct way to say all this is, but I know that it can be done. :)
