I just asked whether this was possible in a previous email, but you must
have missed it. I am seeing a lot of memory management stuff in
profiles, so I think recycling routing cache entries (if only when the
table is full and the garbage collector would otherwise need to run)
would be very helpful.
Is it possible to get a good guess of what cache entry to recycle without
walking for a while or without some kind of LRU?

Not running the important stuff with SMP yet, so I don't care about this
at the moment. O:)
