Comment (by nickm):

 I asked dgoulet what he meant by "unstable", and he said that they are
 ones that come and go often.

 I wonder: do the relays only seem to come and go because of this bug?  Or
 do the relays cause this bug by starting and stopping a lot?

 One possible cause for this bug would be if there's some problem with
 keeping keys and certs in sync as we save them to disk, reload them,
 generate new ones, etc.
