Re: What is the scheduler type of GHC?

Additionally, the current scheduler is round-robin with some heuristics for when threads get to "cut the line", so we do not have priorities for threads. I'm currently working on a patch which allows for more flexible scheduling.

So which is used by GHC? From ghc wiki about rts, if the question is only within haskell threads, it seems like cooperative. GHC is pre-emptive, but see http://hackage.haskell.org/trac/ghc/ticket/367.
