Connections were being garbage collected while they were still in progress since the object would leave scope. This commit adds ObjectWrap::Attach() and ObjectWrap::Detach() to tell v8 that an object is currently on the event loop and will be needed in the future. Other changes to oi_socket.c and net.cc are to fix bugs encountered while running the HTTP server.
