Aha, so when AM is busy horking the processor continuously in hi-res 
mode for its rendering, the system hardly ever gets to step in and blit 
results to the screen.  (Does lo-res drawing somehow bypass this 
mechanism?  It seems to not suffer from this restriction, and also tends 
to "tear", both of which suggest that it might?)

Ah but surely you mean (by telling SDL to SetVideoMode to a full-screen 
mode with page-flipping), or something like that.  ;)

Makes sense.
