Ah, I see.  Hm.  I was about to say that creating a symlink is an atomic
operation, but now I realize that in this context it isn't, because we
would need to remove the symlink first before creating a new one.

But somehow it's just cool to abuse symlinks for this :-)

    rm -f ~/.xmonad.dynamiclog
    ln -s " 1 [2]<3> 4 // xterm" ~/.xmonad.dynamiclog
