Yes, i'll do my best with the little time i've to continue with sbws.

There's another authority operator ready. If you think we don't need to
fix any bug before a 3rd directory authority runs sbws, i can tell them
to start running sbws.

I'll look at all these bugs more in detail.
How many directory authorities would we like to be running sbws (after
those bugs are fixed) by which date?.

BTW, longclaw's sbws did not have network for ~1 days (which for sure
has affected to some metrics), i should have documented that somewhere,
not sure there's a better place for that than trac.

Thanks,
