Multiple user request in course 'Build a Simple Dynamic Site with Node.js'

The course is 'Build a Simple Dynamic Site with Node.js' by Andrew Chalkers, the lesson "reading Files".

Just load and finish the code created by Andrew (remember to replace HTTP with HTTPS as a result of recent changes in Treehouse) in Profile.js and then run the app on localhost with Chrome. Keep switching between real user (chalkers) and fake user (chalkers123) back and forth. Ultimately the app will crash. I tracked down the error and what's happening is that when I put a real user (chalkers) after putting a fake user (chalker123) the browser is issuing two requests at the same time for chalkers, with the second while the first is still running. As a result the second request overlaps with the first and it crashes with message "write after end". Andrew in his testing runs each case just once. I wish he tried to run them back and forth several times. Anybody run into this problem? Should I try to fix it, or just ignore it and proceed with the course?

Thanks, Cezar
