Thanks, in the mean-time we can do the review here.

As regards removing Updator then this is part of the problem as it's too 
fragile to map to opcodes when queuing the change. Also it doesn't take 
account of the possibility of that interestOps might queue a change at 
just around the time that the channel is being removed. The new 
implementation also avoids needing to create an Updator for each change 
to the interest ops.
