Zach, Do you have any userspace code that can be used to get started experimenting with your fibril based AIO stuff? I want to try it on from a userspace perspective. I'm confident I could hack it up from scratch, but I'm sure you'll have some test code lying around. I scanned the discussion so far, but I might've missed any references to userspace code so far.
