Patch Set 1:
I am not sure, if the title object should allow access to internal cache logic. Other parser functions are using its own (static) cache to detect duplicate calls (see pagesincategory for example), than you can also cache the implode, but maybe get a increment of the count, when the own title of the page is used.
