This deals with the fatal DMA errors on my machine.  Well done.

However, fixing this bug reveals something else.  After about 2 hours of
streaming on MLB.TV I got this, apparently at random (but this is not a
hard error: by disassociating from the AP and reassociating, the rest of
the game played fine, and there was no need to load or unload modules):
