Unfortunately it seems that forkIO'ed threads are freezed when GHCi is waiting for command-line input. I bet it would be possible to let the threads work in the background. I think the current behaviour is caused by using readline, which is a foreign library. Or it is by design?

I also think this is unfortunate, and would like to know if this can be worked around (ie. I could happily live without readline if that is the issue and it can be switched off).

The fix is trivial: we have to add -threaded when we link GHCi. The only reason I haven't done this yet is because I'm being cautious; the threaded RTS is a fair bit more complex that the non-threaded RTS. I think we'll schedule this for 6.6 though. Cheers, Simon
