I don't know how rare the case is. It might become less rare if there is an
uploader of big movie files and it's easy to overwrite the big movie file by
hitting 'save' button in movie editor while it is still uploading... Perhaps
such uploader can use other means to detect the file change though...

It would be nice to spell out *some* behavior though, or we can end up with
some incompatible implementations. Speaking about Blob.slice(), what is
recommended behavior of resultant Blobs on the underlying file change?
