Comment (by nicklas):

 I'm not sure I understand this right but if I do, wouldn't it be a
 solution to do like this:

 detect the fenomena; if this stabline intersects a paralell edge then the
 start and end of that edge have to be on the stabline too. So if both
 start and end intersects then the alarm should go.

 then when we know it has happened, in't it possible to just give the
 stabline a new direction and give it a new try?

 I haven't studied the code and have just understood the pricip of the
 process from your comments Paul, so if I missunderstand it all, I hope the
 world will continue rotating anyway.
