I have a minor issue with the variable naming, IMHO it violates
the rule of "least surprise", short names are normaly used for
integer loops like for(i=0;i<10,i++). Perhaps some kind soul
can change that into something more readable >(eg. info, node,head).

note: this comment is not directly related to the patch, just
       my 2 cents
