The "Half-Baked Code" Challenge

Think you can spot the memory leak in this Node.js stream implementation? It survived code review, but it will crash the server under load.

server.js

const server = http.createServer((req, res) => {
  const stream = fs.createReadStream(filepath);
  stream.pipe(res);
  // This code passed code review.
  // It will crash your server under load.
  // Can you spot why?
});
