	I had struggled with the same problem a year ago, and I concluded it 
was hopeless. See

http://www.haskell.org/pipermail/haskell-cafe/2010-January/072193.html

	The only stream processors that conform to the Arrow interface seem to 
be the FRP-like ones, where each stream item comes with a time stamp. 
I'm not entirely convinced that Arrow is the best abstraction even in 
that case.
