The 'main' thread in GHC is the bound thread initially allocated to the process. You can easily establish an event-loop in the main thread, and feed events from other threads. Consider using Control.Concurrent.Chan. If you need feedback, things get a bit trickier because you'll have special cases based on whether you're starting in the main thread. Regards, Dave
