No, I think that is a non-starter. Doing synchronous IO has been explored before in other APIs and thoroughly abandoned. I don't feel like looking up a link now (you can probably do a search on the whatwg archives for 'synchronous'), but basically: * Disks can get busy, so even if an operation is *normally* fast, it won't always be * Disks can be remote, mounted over a network - a
