But your set_line routine utterly confuses me. Seeking goes to *byte* positions - it has no idea what a line means.

Well, since i know the line i'm currently and i know the line i want to be is smaller, i rewind the filehandle. Seek does that nicely (and fast, unless i'm mistaken).

However i still read with readline(). Basicly that causes io for all line. Since io is slow and i don't really need the lines between 0 -> wanted (or current -> wanted), i think there should be a way to move faster between newlines *shrug*.
