But what exactly does show() do that prevents it from being called again? At
least for the Mac OS X and the gtkcairo backends, calling show() multiple times
doesn't seem to cause any problems. Can you give an example where calling
show() multiple times breaks things? If there is such a case, it may reveal a
lurking bug in show() itself.
