Seems reasonable. Best to keep it simple. If you're submitting a job with
"job-hold-until" you'd be well advised to use a notification different
delivery method like email. But we probably need some way to "expire"
undelivered notifications, so they don't build up indefinitely if clients
go away. Could be a simple, specified maximum guaranteed retention time
for undelivered notifications, or an attribute (settable or not).
