Looks ok.
I wonder why the patch does not contain any test modification.
What about the tests added in https://github.com/whatwg/streams/commit/2e7f87e45806d58114592c923aed299798d10161?

You're right, I saw them at that moment and I forget about them later.

Are we not already passing this test without ReadableStreamInternals.js tests?

Are we not passing this test without the patch?
The checks of this test may not be sufficient enough.
It seems to me we should check that rs.getReader().closed be equal to theError.

Both fail in debug because of the assert, but not in release.

r=me.
It would be good to improve the second test: making it a promise test, expecting the error to be theError and not a RangeError, either here or as a pull request to whatwg streams github.
