kevent returns an EV_EOF after server closes the socket.

[Luke Small]

I have a program in which I make a read kevent to identify an early EOF
event on the client side of the socket. Server enters a loop in which it
sends a message to a client and I even EV_DELETE the offending kevent and
close the socket, before it ever gains access to a kevent call which reads
the kqueue, but it still returns an EV_EOF after I've done all that, as if
once it detects that the client EOF the event cannot be turned off as
described in the man page!
