Bird 1.5 and 1.6 memory leak

I had to reinstall version 1.5.0, to remain in the ubuntu default PPA.
The route count is ridiculously low though:

         $ birdc show route count
         BIRD 1.5.0 ready.
         11 of 11 routes for 11 networks

It seems to leak at the kernel level, as the process memory doesn't 
increase.
I'm not doing any reconfiguration. It increases gradually and is closely
tied to the traffic crossing the router.
If I stop any traffic from passing (eg, using iptables), the memleak 
stops.

As I said, I also don't have this leak if I leave bird down and 
configure
the routes statically.
