But I think not using the blob URL on a different origin is ok? You can always
postMessage the actual Blob, and then mint a Blob URL for use with *that*
origin, though.

Also, as it currently stands, the specification does nothing more significant
than equating the origin of the Blob URL with that specified by the incumbent
settings object for the script at the time the create* method was called. IMHO
that makes it pretty clear how to extract the origin, no?
