Just downloaded MacHg 0.9.20. I now have six "Loading Repository Information" messages that don't seem like they're ever going to complete. As far as I can tell, it seems MacHg is simply comparing the selected repository to others to what has to be pushed/pulled to make them the same. Although I can imagine circumstances under which this operation might take a long time, it seems that it should be killed as soon as the focus is moved to another repository, so that I should never see two such messages at the same time.
