Quoting from the documentation: forkProcess :: IO () -> IO ProcessID [...] On success, forkProcess returns the child's ProcessID to the parent process; in case of an error, an exception is thrown. What I assume is happening is this: The child terminates _right away_, with a non-success error code, no less. And my guess is that forkProcess interprets this as the /fork/ having failed and throws an exception. The following program, for example, works fine: > import System.Exit > import System.Posix.Process > import Control.Concurrent > main = forkProcess (threadDelay (10*1000000) >> exitFailure) Peter _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
