I like having loading pages displayed during longer macros as it lets the end user know the system is not available for them to control during that time. The only issue of course is if the page the user ends up on offers the ability to browse backwards. If so, browsing backwards takes the user to the last of the loading pages just as described by the OP. Browsing back through the loading pages in reverse order at the end of macro sequence while at the same time forcing each loading page at that point to appear just like the last loading page, this is a very simple solution implement. Takes the user right back where they started while at the same time clearing the browse backwards stack. Time permitting I'd be happy to provide the OP with an example configuration file if they are interested.
