> It's possible for the slave to be overcommitted (e.g. MESOS-1668). In the case of "named" resources like ports and ephemeral_ports, this is problematic as the resources needed by the tasks are in use.
> This ticket is to present the idea of rejecting tasks when the slave is overcommitted on ports or ephemeral_ports. In order to ensure the master reconciles state with the slave, we can also trigger a re-registration.
> For cpu / memory, this is less crucial, so preventing overcommit for these will be punted for later.
