The main reasons for me to suggest that was that in case of exceptions and
asynchrounous sockets is that its the exception could be thrown
asynchrounously in a thread that didn't make the request but in the one
dequeuing the completion. And that it is hard to associate the socket
instance with the error in case several sockets is associated with a
reactor/proactor instance.
