Re: [Haskell-beginners] Parallelism?

Excellent! Glad this has been sorted out upstream. Edward, to answer your question regarding blocking database calls: I'm using mongoDB to log events that come into a WAI webapp. The writes to mongo are blocking, so I'd like to run them in parallel with the webapp. The webapp would push the data into a Chan and the mongo writer would read from the Chan and make the writes sequentially (using the Chan as a FIFO between parallel threads). This would allow for request rates to temporarily rise above mongo's write rate (of course with an expanded memory footprint during those bursts).

Simon Marlow investigated, and we got this patch out:

Nice work, guys! Hope it gets included in the glourious GHC 7.4 =D.
