I took out a wristwatch and timed it instead of guessing.   I get three
frames per second.  It's about 4x from where we started, but still slow.  I
guess I'm just underpowered, although a couple of years ago this was a
powerhouse.  It seems that matplotlib may not be suited to this task.  I
don't think it should take 2 GHz just to power a stripchart.

I've got new hardware coming this summer.  I get whatever IT gives me (until
I can find funds to buy my own), so I don't know what I'll be getting.
We'll see what happens.

I have another question, but I'll start a new thread for that ...
