clarify the example presented where multiple REPL
instances are run in the same process by:
- making its title unambiguous
- clarifying that they share the same `global` object
(which currently is a bit ambiguous/half implied)
- making sure that they do share the same `global`
object (via `useGlobal` set to `true`)
- they delete the unix socket if present
(so that people running the code twice don't get
confused/annoyed that the second time it doesn't
properly work)
