The way it is supposed to work is exactly the way it did work; first (and last) 
there is a lot of discussion; at some point a member of the style council (in 
this case, me) decides this is close to consensus, but not quite there, 
presents the alternatives in summary form, and sets some sort of deadline for 
consensus or voting.  People realize that they really could live with the other 
option, a consensus is reached, and no voting takes place (it's magic!).

Now let's say that a consensus is not reached, because Jamie (the only person 
who objected to (disc #) in single titles who hasn't yet replied to my summary 
message) feels that it would cause irreparable harm to the purity of 
MusicBrainz's bodily fluids to allow (disc #) in single titles.  If it's just 
one person who objects, we might still have consensus, but if he feels strongly 
about it, and is a style council member, and is an editor for the relevant 
area, we could certainly have a vote if he requested it.

At that point, the three people would meet on IRC or by e-mail and vote on the 
issue (no abstaining, no ties - that's why there are three).  This decision 
would be "final" at least for the moment, until there is some new proposal that 
hasn't been considered before, or other changes (e.g. to tagger functionality).

Once consensus has been reached (usual case) or it has gone to a vote (rarely), 
the last thing that needs to be done is to update the Official Style 
Guideline(s) that are affected by the decision, in this case, 
http://wiki.musicbrainz.org/wiki.pl?DiscNumberStyle - where John has already 
put some notes on (disc #) in single titles.  Those notes should be updated to 
reflect the decision, noting some of the problems (e.g. differences between 
multi-disc singles and singles with disc #s that are sold separately should be 
noted in album annotations; assumption now is sold-separately, for singles).

John would be the logical person to do this last step, but as he's away for the 
weekend, Jamie or Stefan would be the next choices, as responsible editors.  If 
neither of them gets to it, I would be the one who can't pass the buck...
