Notes
mk_timer_arm replaces any previous deadline on the port with a new absolute one. When the deadline elapses the kernel enqueues a single mach message on the timer port; the caller must mach_msg_receive it. There is no repeat mode at this layer — repeating timers are implemented by re-arming from the message-receive callback.
