I'm thinking, there are too many programs that hang when I want to end 
them just because some thread inside is waiting for a socket. I think 
that any operation that could block for an arbitrary amount of time 
should be disallowed during shutdown.

What sockets library do today is, they offer a global close_library 
function. Once that is called, all pending socket connections and all 
new socket connections fail immediately.
