What I meant is that it would be good for the above pattern to work, and
not cause an IO error.  For example, you can have a black-box API call that
takes a blob or a blob URL, and happens to start an XHR inside the black
box.  The caller of the API can close the blob (or revoke the blob URL)
after calling into the API without interfering with the XHR that it doesn't
know about.
