2 - Be more generous with how much bandwidth we'd use up (with
3 accounting enabled) before entering "soft hibernation".
4 Previously, we'd hibernate once we'd used up 95% of our
5 allotment. Now, we use up 95% of our allotment, AND make sure
6 that we have no more than 500MB (or 3 hours of expected traffic,
7 whichever is lower) remaining before we enter soft hibernation.
10 - For bandwidth accounting, calculate our expected bandwidth rate
11 based on the time during which we were active and not in
12 soft-hibernation during the last interval. Previously, we were
13 also considering the time spent in soft-hibernation. If this
14 was a long time, we would wind up underestimating our bandwidth
15 by a lot, and skewing our wakeup time towards the start of the
16 accounting interval. Fixes bug 1789. Bugfix on 0.0.9pre5.
