thanks.  it will certainly affect us, certainly in a good way.  the
facilities for suspend management are vastly improved in newer
kernels, and we're planning on taking advantage of that for 1.75, and
hopefully soon for 1.5 and xo-1 as well.  when dust from the thread
being discussed by corbet settles, we'll start planning on taking
advantage of those facilities too.  given that our current
implementation is based on the prevously available rocks and stones
held together with bits of chewing gum and string that we provided,
i'm not too worried that we can't do better with what's coming along.
