Hey all,

I'm playing with Riak via the haskell client, and I've run into a problem

job with a connection, I only ever see results from that job.

which exhibits slightly different behaviour to my application code. In the
small example, I'm seeing results from the second query twice. I think there
might be something going on with laziness, but it's beyond my ability to

Any pointers? This is somewhat specific to the haskell client, I hope this
