There is a :display-time initarg for panes. It controls when 
the :display-function is called.

But, there is a handle-repaint method (which is a part of Sheet Repaint 
Protocol) that does the repaint. As I understand, :display-function is a more 
high-level (it's defined for stream panes), and it outputs not pixels on 
screen (which is a job for handle-repaint), but outputs objects onto pane.

(I myself do not have a good knowledge of CLIM, so whatever I say might be 
wrong).
