This mornings magic numbers are:

 ip_dst_cache        1292   1485    256   15    1

I just did a q-n-d test here: send one UDP frame to 1.1.1.1 up to
1.1.255.255.  The ip_dst_cache grew to ~15k entries and grew no further.
It's now gradually shrinking.  So there doesn't appear to be a trivial
bug..

 Is no one interested in the fact that the DST cache is leaking and
 eventually takes out machines?  I've had virtually zero interest in
 this problem so far.

I guess we should find a way to make it happen faster.

I could be a refcount problem. I think Russell is using NAT, it could be
the MASQUERADE target if that is in use. A simple test would be to switch
to SNAT and try again if possible.
