Comment (by arma):

 I have been running my {{{ticket4631-demo}}} branch on moria1 lately, and
 it is catching and handling real buggy behavior by other directory
 authorities:

 It would be swell for somebody to turn it into a branch that the network
 team is willing to merge. I don't think it would fully resolve this ticket
 but it is a nice step.

 And in the mean time, other dir auths, if they're ok with manual patching,
 might enjoy running it.
