Does it need to be in the kernel? Sleep for interval seems trivial- don't
bother scheduling the process before that time. Sleep until wall time is
just as easy, a scheduler can keep a linked list of processes to be
woken up and check it against a time server every now and then.

We will need to checkpoint wall-time scheduling requests, though.

Is there some conceivable reason that won't work with the way sched-
uling works today?
