I'm a bit worried about races if you mix scheme (a) with the replots
done under scheme (b).  

What happens if somebody resizes or otherwise triggers a replot on
an old window while you're processing a new palette in the main pipe.
Will that corrupt the new palette forever after?

What if someone closes an old window (the only remaining user of
a palette) just as you start to get a new copy of that same palette.
Can you end up with no copies?  Two copies?

Maybe I worry too much.
