Okay, there's an actual bug here as well. Doing a read on a non-blocking socket may raise EAGAIN / EWOULDBLOCK if there is no data available, and we weren't catching that case. I'm not sure why I didn't see this when I tested this the first time, since it's a pretty pervasive failure.

It's easy to patch this, but I wonder what the performance cost will be of catching errors vs. doing a select first to see if data is available, since raising an error is the common case.
