-- Requests a reboot of the specified instances. This operation is
-- asynchronous; it only queues a request to reboot the specified
-- instances. The operation succeeds if the instances are valid and belong
-- to you. Requests to reboot terminated instances are ignored.
--
-- If an instance does not cleanly shut down within a few minutes, Amazon
-- EC2 performs a hard reboot.
