That is one of the things I don't like about LuaSockets: AFAIK there is 
no way from Lua to make the socket nonblocking. By nonblocking I mean in 
C "fcntl(socket_fd, F_SETFL, flags|O_NONBLOCK)". When I want a 
nonblocking socket, I want to say in Lua "sock:setnonblocking()", and it 
stays nonblocking.

The second thing is that all error codes should be returned so they can 
be dealt with.
