Did you read the paper Extending the Haskell Foreign Function Interface with Concurrency, described in the GHC Wiki page about concurrency? It'd be a good start http://hackage.haskell.org/trac/ghc/wiki/GhcConcurrency Please do improve it.

According to Simon PJ, each | foreign call will get its own OS thread if its blocked. | | How does GHC determine if the call is blocked? Does each call get its | own OS thread from the start? Sometime later? Does this depend on the | safe/unsafe specs of the foreign call? | | Does the above change if a threaded/non-threaded runtime is in use? | | Thanks, Joel | | -- | http://wagerlabs.com/ | | | | | | _______________________________________________ | Haskell-Cafe mailing list | Haskell-Cafe@haskell.org | http://www.haskell.org/mailman/listinfo/haskell-cafe
