It (kinda) has multiple cursors per document if you split the frame and display the buffer twice. For longer source files I find myself splitting horizontally, editing in the left pane, and using the right pane for secondary movement and reference. I have a buffer manager that can switch the displayed buffer quickly, when I switch to a different buffer and back again, it retains it's "secondary" cursor position that is separate from the other view.
