I am not expert of task queues, but looking at ur requirment may be u can leave the future task at player's browser. Run a javascript timer at the browser and whenver it timeout inform the server(ajax) and tell the player too. Timer can be set for player's turn and while he is waiting for other player. And ofcourse then u can run task(server side) every fix time to clean games(to set game status as finished/abandoned etc) which have been crashed/browser crash or people have left without clicking proper buttons on ur app. May be it will save someof ur cpu and tasks count/billing :).

Hi, Is there a way to delete or unschedule a task? I've got a multiplayer game. Whenever a player starts their turn, I schedule a task for now + n minutes, where n is the total time they have to perform their move. When the task executes, I check if they have performed the move, if not, I cancel their turn. But my queue will end up having many unnecessary tasks in it: Round limit = 5 minutes queued-task: game=abc, check at 5:00pm queued-task: game=abc, check at 5:01pm ... As each player starts their turn, all the tasks pile on as above. Ideally I only need one scheduled task in the queue at any given time. When a player starts their turn, I could flush the queue of all previous scheduled tasks, which are no longer needed. There doesn't appear to be a way to do this, named tasks block insertion of tasks with the same name, I was hoping to use that as a trick to find and remove or overwrite the tasks with the same name (using the game key as a unique identifier)?
