I don't think the bulk of overhead is from screen_object_list(). Anyway,
I am kind of busy with fixing other bugs. I think we could get good
enough info which is biggest culprit by tracing. For last time I tried
with trace, fill_obj_list() took most of the time, which tried to
connect_to() all the nodes.

Thanks,
