[Bug 25081] Make read operation really async

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25081

--- Comment #28 from Jonas Sicking <jonas@sicking.cc> ---
One thing that we should make sure of is that a URL object which represents a
Blob doesn't hold the Blob data alive. As I understand it that would just be a
waste of resources since once you do

img.src = myurlobject;

we roundtrip through a string, and so if the blob has been closed, or the url
revoked, then the img still wouldn't load successfully. So if myurlobject kept
the Blob data alive it would be for naught.
