Re: [Haskell-cafe] Cleaning up threads

Bas van Dijk writes:

Don't forget to block asynchronous exception _before_ you fork in:

       tid <- forkIO (someWorkToDo `finally` putMVar mv ())

Otherwise an asynchronous exception might be thrown to the thread _before_ the 'putMVar mv ()' exception handler is installed leaving your main thread in a dead-lock!

Good catch, thank you, G -- Gregory Collins
