 ===== Email to Professor Alan Burns =====
-Race conditions might still be in my code, because my code is crappy, and my knowledge is shoddy. I have emailed my undergraduate professor - hopefully he will give me some help. Hopefully, at least he would find my story funny -- I know at least if someone send me an email like this, I would love it.

+==== Professor Alan Burn's reply ====
+<code>
+Hi,
+Thanks for your 'story', indeed ironic but interesting - I am pleased to have had a possible input.
+Deadlock detection is VERY hard - testing will not identify the subtle situations that can lead to this failure
+Two approaches - one use a resource usage protocol that prevents deadlocks (they exists for single processor
+systems but are not as common for true parallelism) - two, use model checking on a model of your software
+to 'prove' deadlock free in ALL circumstances. The latter is a powerful but not too easy to apply, especially to
+code that already exists.
+Good luck
+Alan

+Chris Lamb was the Debian Project Leader in March 2019. In his blogpost, he mentioned ''httpdirfs-fuse''. This is really cool!!! It feels like I unknowingly got an autograph from a Hollywood star!!!
