  I'm afraid you misunderstood what I meant by "Giant leak." :-)

  I was referring to a potential leak of the Giant _lock_, not a leak
  of Mbufs and Clusters.  But what you are seeing seems to very much be
  an Mbuf leak, at least, and should be investigated.

  Please cvsup to -CURRENT (follow the -current mailing list to figure
  out when it should be reasonably safe to do so) and verify whether this
  problem has been fixed, as it is posssible that it already has.

  If not, collect as most data as possible and get back to me.
