Hm.  I think the idea was that rather than setting it to "something very
large", you'd want to just disable the feature via vacuum_cost_delay.
But I agree that the threshold for what is ridiculously large probably
ought to be well more than 5x the default, and maybe it is just mindless
nannyism to have a limit less than what the implementation can handle.
