Maybe it's worth adding some text in the comment here to explain why this is
needed--that renderer processes can be re-used so there can be multiple world-0
instances (for different extensions) in the same process.

Also, can you end up with collisions among non-zero worldIds?  Why not, or why
isn't it a problem if it happens?

Done.
