(Disclaimer: I work for Google, but have no inside information about
Chrome or V8.)

As I understand it, each tab (and a fortiori each window, with some
exceptions) is a separate OS-level process, and shares nothing except
the code segment and, transparently, any COW data that may exist under
operating systems that support it.  Consequently, there is no reason
for V8 to do anything special for concurrency, as the only concurrency
present is that needed for timers etc.  I don't know whether the
in-memory page cache is shared or not.
