(Untested code)

class ProgressReportingStringPager(StringPager):
    def __init__(self, ui, *args, **kwargs):
        self.ui = ui
        StringPager.__init__(self, *args, **kwargs)
        
    def nextPage(self):
        StringPager.nextPage(self)
        self.ui.reportProgress(self.pointer/len(self.string))

I haven't tried, but it looks like something like that code could easily
give you progress reporting from your pager.  The paging code is really
quite simple.
