Sorry about that - it was an oversight that I missed in the 
implementation and only noticed it when you exposed how IoFuture 
violates contract for cancel. The technical reason is of course that the 
forceful cancel is closing the channel but isn't setting the result or 
waiting for the result to be set. I've fixed this and so it will be 
included in the next drop and build (probably after JavaOne as there is 
too much going on just now).
