Essentially not at present; but it's high on our list. Because of the fun we've been having with Software Transactional Memory (STM), which will be in GHC 6.4, and because of the multi-core machines that are coming right now, Simon and I are starting to think much more about genuine hardware concurrency, esp on multi-cores. We have not actually done anything yet, but I think we will soon. STM is described in a PPoPP paper on my home page http://research.microsoft.com/%7Esimonpj/papers/stm/index.htm Simon | -----Original Message----- | From: haskell-bounces@haskell.org [mailto:haskell-bounces@haskell.org] On Behalf Of S.
