I've rebased patch (see attachment), it seems to work. It still requires a bit of styling, docs and tests, at least.
Also, I thinks that hash table is not very good option if we have all pages there: we should either use array or do not fill table for every page.
If author and community do not object, I want to continue work on Konstantin's patch.
Best regards, Andrey Borodin.
