[lldb-dev] "step" threading issues

You should only get one stopped event unless you are hitting a breakpoint that continues your target. In this case the eStateStopped event would be a "restarted" event which can be found out by:

    static bool
    SBProcess::GetRestartedFromEvent (const lldb::SBEvent &event);

This means the program stopped but restarted automatically. You should never see two eStateStopped events in a row, if you are, please try and reproduce on a Mac target and file a bug.

For step into, the stop reason should always be eStopReasonPlanComplete.
