[lldb-dev] Process launch view duplication

[Jim Ingham via lldb-dev]

Generally, the driver will print stop info every time a stop event is forwarded from the private event queue to the public event queue.  You can check the output of the event log (log enable lldb event) to see if you are indeed sending two events.  If you are sending two events, you can add the -S option to the log command to see the stack trace when the events were broadcast to the public event queue and see if there's an obvious way to suppress one of them.
