  SVN rev 217916 on 2011-01-27 00:34:12Z by mdf
  
  Explicitly wire the user buffer rather than doing it implicitly in
  sbuf_new_for_sysctl(9).  This allows using an sbuf with a SYSCTL_OUT
  drain for extremely large amounts of data where the caller knows that
  appropriate references are held, and sleeping is not an issue.
