They are never called becuase while doing emulation their is technically no way to get to any other apps. The Emulation is in full control drawing directly to the screen. Didn't wan't to waste any resources to check for other activity becuase no other activity can really happen At least that was the theory. I could add them for complete code but I just never did.

Wrong. This hack was used becuase myself and many others including the developers of PocketTV and Rocket Elite to name a few, detected an obvious bug in the 3800 series. I am not sure of the details of whyu or how this bug works (Check the Brighthand Boards thats were I saw the explanation). All I know is that something to do with the lookup of the frame buffer takes a whole lot longer on the 3800 than it did on the 3600 series. Therefore the Developers of PocketTV came up with this hack to speed things up (which it does significantly). When I get time I will be testing your comments on the SHFull and I will test it with both the default settings and the hack, but I suspec the hack will still be needed.
