Nice, I've been waiting for this for a while. Well, sorta waiting. It
turns out that the battery life on my Acer Pentium M laptop is so good
that I can estimate when it'll run out mentally. "Has it been more than 2
hours since I wandered away from an outlet? Hm, maybe I should return."
Now I just have to wait for this to be MFC'd to RELENG_6. :)
