Adjustment to 218194. There was a concern that there might be IBreakpointListeners out there that are interested in the INSTALL_COUNT attribute, since that attribute was defined in a public interface. This new solution is a hybrid between the original logic and the initial fix to 218194. We don't use the INSTALL_COUNT attribute to maintain the install count, but we update it when it changes. I've updated the documentation for the attribute.
