Howdy, I've got a question about threading and thread models in ghc-iphone. My understanding is that Haskell has its own threading model that under the covers uses OS threads, but allows for significantly more active threads. Is this a correct understanding? If so, how does the Haskell threading model work on the iPhone? Is it that iOS is close enough to OS X/Darwin that it "just works"? If it "just works", then how does one marshal an event back onto the iOS "UI thread" so that the display or draw or whatever command can take place on the UI thread? Is there a convention or recipe for doing so? Would it be possible to put an event on the UI event queue that applies an Haskell closure such that the Haskell code that contains the computed value (I'd force the computation before marshaling the event to minimize the actual delay on the UI thread) then mutates the UI based on the computed value? Given the 5 second rule about an iOS app getting shut down... if there are Haskell threads doing Haskell-y kind of work, is there a way of notifying those threads en masse about the shutdown?
