more on weird resets

Hi all,

I dug out my old trusty veroboard-based proto board (with header pin
blocks for running all the ports out to breadboard). Try as I might, I
can't reproduce the random reset problem on that board.

Guess I might need to do a whole new board, with all the ground traces
flooding out to eat all the unused board surface.

Any further suggestions?
