Hey Roger.  Thank you for reaching out.  All we know is that, in deltas
send from the all watcher, new units started appearing before their
associated services.  We simply sorted the deltas before passing them
through the GUI's pipeline, and that solved the problem (and hopefully
similar problems in the future).
