I didn't see any non-termination instances. Everything looked as expected. The only performance issue I saw was that my plots with shading "seem" to be slower. But, I would have to look at it more closely to see if it was because of other things running at the same time. [My work laptop is just a dual core and something else may well have been running in the background.]
