Well, I don't know the answer to your question, but you can easily find this out by simply writing some test pages with locks, and running them to see what happens. For example, you could place a lock around a long-running loop, and run that from two separate browsers, or even from one browser using a frameset. The answer that you get this way will be more reliable than any provided by the documentation, which often contains omissions, ambiguities, and even the occasional error.
