The current implementation requires some "tension" (via CGlue) on the
pin to keep it from falling back to its rest position in the pad or
slot.  If you're implementing boxes-and-arrows connectivity, then you
might define a link-like component that interposes a piece of only
slightly elastic CGlue between its two pins.  When you connect one of
the link's pins to the pad, the glue will keep the pins as close
together as possible, thereby drawing the pin away from the rest
position.

The latest version of drawing demonstrates how this is done with a
slightly modified version of LinkComp.  You can ftp it from
interviews.stanford.edu in pub/contrib/drawing-3.1b.tar.Z.
