 const bodyParser = require('body-parser');
 const { EventEmitter } = require('events');
 
 // Aggregate all profiler results into an event emitter to make
 // handling the results generic
 const profiles = new EventEmitter();
 
 profiles.on('middleware', ({ req, name, elapsedMS }) => {
   console.log(req.method, req.url, ':', name, `${elapsedMS}ms`);
 });
 
 app.use(wrap(function block(req, res, next) {
   setTimeout(() => next(), 1000);
 }));
 
 app.use(wrap(bodyParser.json()));
 
 app.post('*', function(req, res) {
