 +==== 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

 +===== HTTPDirFS was accepted into Debian repository by the then DPL himself! =====
 +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!!!
