Without revoking the UA has to keep around the URL-string -> resource
mapping for the lifetime of the page. Which in the world of web apps
can be a very long time. Even worse, in the case of dynamically
created blobs (blobbuilder, canvas.toFile/toBlob/getAsFile whatever
we'll call it), the resource has to stay around at least on the users
file system for the lifetime of the page.
