not really related to this path: I was wondering if this is still true after the
recent patches, i.e. that m_monitor can be null during testing..

I don't think this ever was true. In tests m_monitor never connected to
anything, but it was still non-null. Removed all the checks for that.

     if (m_monitor)
         queryNextStatus();
