With full respect, "extra delay" being a subjective term, etc,
but do you have any idea how long it takes to fsck a 20TB filesystem 99% full
with a mixture of small and big files? (Hint: it takes more than 30 seconds).

But I guess it is the modern view of things: "if it is quick on my laptop
it would not cause much extra delay for anybody else". No need to put numbers on it
or think about scaling (at least fsck is mostly O(n) in disk size).
