TCPSocket.open with a running server
- silently ignores 'nil' as the third parameter
- connects to a listening server with host and port
- connects to a server when passed local_host argument
- connects to a server when passed local_host and local_port arguments
- has an address once it has connected to a listening server

TCPSocket partial closability
- if the write end is closed then the other side can read past EOF without blocking
- closing the write end ensures that the other side can read until EOF

TCPSocket#recv_nonblock
- returns a String read from the socketrbx: vm/builtin/variable_scope.cpp:143: rubinius::Object* rubinius::VariableScope::get_local(int): Assertion `!isolated_' failed.
