\definetextbackground works :). The following works correctly (breaks 
across pages, and does not give false blank pages)


\definetextbackground
   [example]
   [width=\textwidth,
    background=color,
    backgroundcolor=lightgray,
    frame=off,
    leftoffset=1em,
    rightoffset=1em,
    location=paragraph,
    after={\blank[small]},
    before={\blank[small]}]


Thanks,
Aditya
