There were still times when my screen would go blank, even after the
machinations above.  The final solution was to add these lines to my
.xinitrc:

setterm -blank 0 -powersave off -powerdown 0
xset s off

I think that the first actually stops the screen from blanking in the
console, but whatever the reason, this works.
