A-ha! I was looking for that in the corosync.conf man page shipped with 
Ubuntu 14, which of course ships corosync 2.3.3. Silly me!

So with the right man page, that's indeed spelled out under 
"token_coefficient". Thanks!

Actually the man page I see for 2.4.2 does mention this :) so I guess we 
should simply comment out our setting for "consensus".
