 /** FIXME: This class needs rework, since at present it is not true model.
     Client cannot just obtain frames by grabbing a thread and listing
     children. It should first setCurrentThread beforehand, and it is the
     method that will actually fetch threads. Therefore, if this model
     is submitted to plain QTreeView, it won't work at all.
 
     Ideally, this should hold current thread and current frame numbers,
     and only fetch the list of threads, and list of frames inside thread
     when asked for by the view.
