 Replying to [comment:7 bi0xid]:
 > I have used filosofo's implementation in .diff. I think it prevents
 endless recursion and database problems. What do you think?

 It will create and endless loop given the following data:

 {{{
 Cat1->parent = Cat2
 Cat2->parent = Cat3
 Cat3->parent = Cat1
 }}}

 calling {{{get_category_root($cat_id = }}}''id of Cat1''{{{)}}} will
 create an endless loop.

 Maybe that gives you an idea. What I like is that it resolves linear so
 far.
