  Log:
  1)	Use a more consistent page wait methodology.
  2)	Do not unnecessarily force page blocking when paging
  	pages out.
  3)	Further improve swap pager performance and correctness,
  	including fixing the paging in progress deadlock (except
  	in severe I/O error conditions.)
  4)	Enable vfs_ioopt=1 as a default.
  5)	Fix and enable the page prezeroing in SMP mode.
  
  All in all, SMP systems especially should show a significant
  improvement in "snappyness."
