Comment (by asn):
I'm really tempted to suggest the latter option here, except if someone
(who is not me) wants to take this on.
Fixing this up requires fighting with the bandwidth equations to ensure
that the fix works, and that no other bugs are lying around. I've had bad
times everytime I tried to test the bandwidth equations, since their
behavior is different between chutney and the real network and bugs that
appear on the real network might not appear on chutney (i.e. this bug)
except if you have a big and realistic enough chutney network (the testnet
might be a better test case here, but it still does not contain enough
relays to test all the bandwidth equation cases, etc.).
Fortunately, we are not considering extending the guard lifetime to 9
months anymore, so this is not as crucial as we thought in the past (but
still worth fixing eventually).
