// A WritableStreamTransferringOptimizer is associated with the sink of a
// WritableStream. When transferring the stream in another realm, the optimizer
// is used to construct the transferred stream in the destination realm. Note
// that two realms can be in different threads (in the same process), in which
// case the optimizer is used across threads.
