That's strange. I've always gotten a response from Cloudmade.

My guess is that the routing engine dismisses the jughandle because it is a 
longer route to the crossing point, and only discovers at the crossing point 
that it can't turn left, so it routes onward without considering the jughandle 
again.

I'd just fill in another feedback form. I'm sure they must have overlooked your 
first report.
