I can't find anything about this now, just spent a good 20 minutes searching for it. I guess keywords kqueue, buffer request http are too generic in some sense. :-/

Anyway, the idea was to avoid context switches by waiting/parsing in kernel-side till there was enough data for the client to do something else that just another gimme_more_data()-call back to the kernel.

It could even be applied to other methods than kqueue, so perhaps I remember a bit wrong that this was just for kqueues.
