How fast can you type? The repeat rate of the keyboard is maximum 25cps.
Hardly any noticeable effect due to mode-switching. People should put 
thing in perspective before complaining about rm/pm mode-switching. The 
32-bit platform enhances the performance a lot more than the drawbacks.

3rd possibility; flush the keyboard after each poll (set the head-index 
at 40h:1Ch = tail-index at 40h:1Ah)
