That's interesting, Bulat. Two points I'd like to ask about the streams library:

What machine did you do the IO benchmarks on? Since we get well over 10x
that speed word writing in Data.Binary now, for example, on a fast
machine. (Duncan, what's the max throughput we've seen?)

And secondly, will the streams stuff be updated? I had trouble
benchmarking against it back in January, and am wondering if it will be
