I'm not entirely sure, but it looks like this object is create on the audio
thread and then passed over to the main thread. In that case we should probably
just leave this a RefPtr to the AudioNode? The alternative would be to use a
CrossThreadPersistent that we should be able to allocate on any thread and
deallocate on any thread.

Shouldn't this be RefPtrWillBePersistent ? Otherwise, I guess m_scheduledNode
will be prematurely collected.

yes, this is created on the render thread and passed to the main thread. I used
a RefPtr
