That's not how a worker-based AudioNode would work, it would be a callback in
the worker that can read directly from the input and write directly to the

There are things on the main thread that are not interruptible (layout and
event handlers being the most obvious) so it's only luck if one is able to run
the callback often enough. I can't speak for any other implementors, but I'm
fairly certain it would fail horribly in Opera, as other pages running in the
same process can't be expected to write code to avoid long-running scripts or
expensive re-layouts.
