For the next version of the automatic balloon prototype I'm planning to give
the user-space shrinker a try. It seems to be a better fit, as the current
prototype has to guess by how much a guest's balloon should be inflated.

Also, I think it would be worth it to list possible use-cases for the two
functionalities in the series' intro email. This might help choosing both,
one or another.

Looking forward to the next version :)
