route cache was manifestation of the problem in 3.0.18 not the problem itself. 
You are right of course, there is no route cache in recent kernels but that 
doesn't mean problem should be gone.

In 3.6.10 kernel tries to find IP X on locally connected interfaces (sends  
ARP requests; IP shows up in neighbor table etc), so the final effect is the 
same as in 3.0.18.
