    kernel - Add kqueue support to NFS (fix firefox issues w/nfs)
    
    * Firefox appears to get semi-random memory corruption and otherwise
      implodes if one or more filesystems it accesses does not support
      kqueue.  This appears to be due to some interaction between
      firefox, glib, and the kernel when kqueue support is missing
      from a filesystem.
    
    * Add host-local kqueue support to NFS.  As with locks, the support
      is host-local only and will not work across multiple clients
      sharing the same files.
    
    * Appears to stabilize firefox when file(s) it accesses are on
      NFS.
