As we move from no clients/consumers in kernel voting on corners, to *some* voting and some not voting, we might end up in a situation where the clients which remove votes can adversly impact others who still don't have a way to vote.
To avoid this situation, have a max vote on all corners at init. This should/can be removed once we have all clients moved to be able to vote/unvote for themselves.
