identifierPrefix as an option exists to avoid useOpaqueIdentifier conflicting when different renders are used within one HTML response.

This lets this be configured for the DOM renderer specifically since it's DOM specific whether they will conflict across trees or not.

Added a test that uses two streams/containers that pipe into the same document.

This part is a little difficult to do correctly in practice because there's no explicit signal when a root is flushed. I think the way you'd do that is explicitly wait to start writing until the root is signaled as ready, and then startWriting and assume that it's done writing after a setImmediate tick or something but that's a little flawed. What you probably want is a way to explicitly write the whole root synchronously after it is done loading.

The main pattern we want to support is the legacy synchronous render. This test shows that we can support it for streaming multiple containers though.

Currently startWriting will synchronously emit the root if it's available. We can probably preserve that property.
