Hi Marcelo,

Didn't you say that you have 4000 *k* lines?

Anyway, as Scott mentiones, in emacs 24 the linum packages seems to be
more clever and only creates overlays for the visible area of a buffer.
For example, when opening a file with 1000 lines and enabling
linum-mode, I only have 35 overlays, because only 35 lines are visible
at a time.

Bye,
Tassilo
