Comment (by teor):

 Replying to [comment:2 arma]:
 > I am a fan of "publish a new descriptor for sufficiently-changed
 bandwidth estimates if your uptime is less than 24 hours, else assume that
 things are sufficiently established and the next regularly scheduled
 descriptor update will be enough".

 I can imagine two pathological cases here:
 * relays that reboot (or hibernate) every 24 hours, and
 * relays that hibernate or go offline, rather than just having started.

 We'll need to account for both these cases, but they'll make the relay
 lose the guard flag, so we don't need to be so concerned about them.
