This could be a problem.  I was taking the caching to be remembering 
which route was chosen and believing it to be associated with a specific 
source IP address.  I can see this being a very large issue when trying 
to do load balancing.

In light of this information, I think that better could be done in 
Netfilter.  However if there ever was a way to have route selection per 
source IP in the kernel, I would be more interested in that.

I wonder if route selection caching would be different in different 
routing tables.  In other words use a different routing table for a 
different (set of) clients.  Thus one cached routing decision per 
routing table which could differ per routing table.
