Typed arrays should become Transferable (ref. http://www.whatwg.org/specs/web-apps/current-work/complete/common-dom-interfaces.html#transferable-objects)-- that is, it should be possible to pass a typed array using postMessage such that control of the data is sent but the array's data is not copied.
After more discussion on public-webapps, only the ArrayBuffer type will be Transferable -- the typed array views will not be. Note, though, that transfer of an ArrayBuffer necessitates side-effects on the views that refer to it, in order to cause their lengths to go to zero. However, this is essentially an implementation detail. I suspect that this bug should be closed, and the work done under Issue 66578.

I wasn't sure which was the umbrella bug.
Done.
