@Ben Bennett 
 Could you help check if this is the correct steps to verify this bug?

That is a reasonable test.  But Phil Cameron had something that would lock it up far sooner, Phil can you tell us what you were doing that hit this bug?

I just ran Webin's test. It creates and deletes routes in a tight loop. I run several concurrent scripts.
