COMMAND: @halt [<object>]
Halts all commands being run by <object>, or by the object running the command if no <object> is given. If the object to be halted is a player, then all commands being run by objects owned by that player are halted. Use this command to stop runaway objects and infinite loops. The process of halting an object involves removing all commands waiting to be run by the object from the queue and refunding the queue deposit. Halting an object does not affect commands waiting on it as a semaphore.
