Keir,

In lieu of the recent emails about ballooning, do you still want me to
look into making the balloon driver back off when it goes down the OOM
path? Or is it better for that too to be taken care of by some of the
higher level management tools?

Ky,

Does your patch address the situation Keir described above?

[ASIDE]
We are also seeing some other issues with ballooning. Not sure if they
are related. The latest one is described here:
