svn commit: r204807 - head/sys/netinet

[Bjoern A. Zeeb]

Author: bz
Date: Sat Mar  6 21:24:32 2010
New Revision: 204807
URL: http://svn.freebsd.org/changeset/base/204807

Log:
  Destroy UDP UMA zones (empty or not) upon network stack teardown
  to not leak them making the VM subsystem unhappy with every stoped vnet(*).
  We will still leak pages (especially as zones are marked NOFREE).
  
  (*) This will also keep vmstat -z more usable.
