Key parsing is slow compared to real mailstation #15

Not sure the source of this. In the internal testing menu it can be very readily seen.

  1. Press Shift+Function+t (LCtrl+Shift+t on msemu)
  2. Power unit on while holding above buttons
  3. Press '3' to enter "F/A Test"
  4. Press '3' to enter "Keyboard Test"
  5. At a reasonable pace, slide finger across a row of keys and see that a lot of them are missed. Real MS picks them up better.

This is likely due to how often SDL key events are checked, not sure.

EDIT: Added step

This is basically no long an issue at this point. No real metric to test against, but there are no real delays perceived compared to real hardware.
