Title: Notification when an action is to be dropped

Hi Sean,

Thanks for your latest changes. The only difference in my fork now is just this revision, which posts a notification when actions are about to be dropped because the undo limit has been reached. I'm using it to release some internal data structures in my application when I'm sure they are not going to be needed any more because the possibility of undoing expired. It's helping my housekeeping a good deal, but I don't know if it would be interesting for a generality of users, though.

Thanks!
