Cool, I'm glad to hear that the API and the example are useful.

That's strange. I've just tried with my bash kernel, which doesn't
implement do_shutdown at all, and it does stop the process correctly (the
server stops the wrapper process, and that automatically causes the child
process to die). I don't know exactly what could be interfering with that,
but I'll keep thinking.

It should work. Looking at your code, you should switch back to the
commented out line that opens and reads the image files, rather than
displaying the filenames. If you comment out the rmtree(plot_dir) line, are
the images being written as you expect?
