https://github.com/joyent/node/blob/ed7fb149a20ee5e7aa9a0574a242a193d7acd761/lib/module.js#L464 As we can see at #465 and #472, I'm pretty sure that there is no dumb and buffering things on Node.js side. Unless there are some magic in the module._compile() as the opposite.
And i totally agree on your opinion. I should ask V8 team about this. I'll let you know later at this thread.
