* real-time processing and output of this AudioNode.
*
* We track the incoming and outgoing connections to other AudioNodes.
* All connections are strong and thus rely on cycle collection to break them.
* However, we also track whether an AudioNode is capable of producing output
* in the future. If it isn't, then we break its connections to its inputs
* and outputs, allowing nodes to be immediately disconnected. This
* disconnection is done internally, invisible to DOM users.
* Outgoing connections have strong ownership. Also, AudioNodes add self
* references if they produce sound on their output even when they have silent
* or no input.
