[xmonad] How to make floats stay always on top?

Hi All,
I have trouble forcing floating windows (for instance, docks or
cairo-clock) to always stay on top.  That is, they stay on top until
another floating window pops up, e.g. any Firefox dialog, or a window
that I'm forcing to float with M-Button1.  To reproduce: put only code
from Layout.Monitor example page into the config file (below), start
cairo-clock, go to Firefox and choose "save as", then click cancel.
cairo-clock will disappear into the background.  Is there a way to fix


import XMonad
import XMonad.Layout.LayoutModifier
import XMonad.Layout.Monitor
clock = monitor {
      -- Cairo-clock creates 2 windows with the same classname, thus
also using title
      prop = ClassName "Cairo-clock" `And` Title "MacSlow's Cairo-Clock"
      -- rectangle 150x150 in lower right corner, assuming 1280x800 resolution
    , rect = Rectangle (1280-150) (800-150) 150 150
      -- avoid flickering
    , persistent = True
      -- make the window transparent
    , opacity = 0.6
      -- hide on start
    , visible = False
      -- assign it a name to be able to toggle it independently of others
    , name = "clock"

myLayouts = ModifiedLayout clock $  tiled ||| Mirror tiled ||| Full
                tiled   = Tall nmaster delta ratio
                nmaster = 1
                ratio   = 1/2
                delta   = 3/100

main = do
	xmonad $ defaultConfig {
                 manageHook = manageMonitor clock
               , layoutHook = myLayouts
