Hum ... got some sleep and I've re-read the GHC documentation on [0]. They say "It is a common misconception that you need to use forkOS instead of forkIO to avoid blocking all the Haskell threads when making a foreign call; this isn't the case. To allow foreign calls to be made without blocking all the Haskell threads (with GHC), it is only necessary to use the -threaded option when linking your program, and to make sure the foreign import is not marked unsafe." [0]: http://www.haskell.org/ghc/docs/6.12.2/html/libraries/base-4.2.0.1/Control-Concurrent.html#v%3AforkOS Does that mean calling `mainGUI` in a program build without '-threaded' blocks all the GHC runtime threads, including the garbage collector ? /John ------------------------------------------------------------------------------ Beautiful is writing same markup.
