As long as these errors are reasonably explainable.
If a strange error only occurs when running nmap on an OS X server, then
it might be useful for the user to know that the OS X server isn't able
to service all connections properly due to a bug in the operating

I am talking specifically about the address being None (i.e., a (sock,
None) tuple is successfully returned).
EWOULDBLOCK and ECONNABORTED are documented error conditions for
accept(), but returning 0 in addrlen is not.

Perhaps it's time to add an alternative handle_accepted(sock, addr)
which relieves the user from calling accept() :))
Then, perhaps self.accept() shouldn't filter any errors at all, but the
default handle_accept() would silence them before calling
