[Haskell-beginners] Pure function with timeout

I read http://www.haskell.org/haskellwiki/Timing_out_computations I thought I saw an issue and tested it: http://hpaste.org/44512/timed_iteration IMO, the timeout function should return the last iterated value when it is signaled, and not the next one after the signal. Is there a convention for this behavior? -- Alex R
