(This bug is lhs)
The following seemingly simple code causes infinite data growth and
resource exhaustion when the code for System.Timeout does not immediately
appear to have a bug with respect to resource utilization.
> module Main where
> import System.Timeout
> import Control.Monad
> timeoutval :: Int
> timeoutval = 12 * 10 ^ 6 -- 12 seconds
> doit :: IO (Maybe ())
> doit = timeout (-1) $ return ()
> main :: IO ()
> main = forever $ return ()
