Userspace likely would not properly handle EAGAIN on a nonblocking socket.
As far as I can tell, either you block, or you have to scan the checksum before
Would it be so bad to do the checksum before marking the socket readable?
Chances are we're going to receive the message "soon" anyways, so there is at
least a chance it will stay hot in the cache, no?
