One of my favourite things about Python is that pretty much everything about the language can be inspected at runtime and today I found out this is true even for threads.
While working on this PR I kept running into issues where the esbonio process would not terminate, despite everything to my knowledge at least, was being shutdown as expected.
Having encountered issues like this before, I knew the culprit was likely to be some background thread was stuck on something and keeping the process alive.
The problem was I had no idea which thread it could be or what it was doing.
