I didn't feel the need to include anything non-cryptographic because points have been made that choosing a cryptographic hash function would be wise (because the feature might be used for something different later, among other things) and worries were expressed that SHA-256 might be too slow. I think these benchmarks show that that slowness is not a real problem, so I think we should pick the right tool for the job rather than try to pick the fastest hash function. It wasn't a contest, just a test to see whether SHA-256 was within the realm of feasibility, performance-wise.
