Libev doesn't do any I/O, and doesn't touch your fds in any way.

I am not sure what the conenction between EAGAIN and the socket buffer
size is (you get EAGAIN or EWOULDBLOCK when you read or write to a
non-blocking fd).

However, libev only notifies you of I/O events, it otherwise doesn't do
anything with your fds, it doesn't even set them to non-blocking mode for
