Forking and Interruption in ZIO

I recently encountered a bug in my application that caused it to hang during startup. The only change made was upgrading ZIO from version 2.0.x to 2.1.0. After some investigation, I discovered the issue was related to how I was forking fibers and a change in the behavior of Reloadable introduced in the new version. Let me explain what happened because I was very much surprised by the unexpected change.

Dissonance

Dissonance implements Eugene Myers' diff algorithm in Scala as a pure function on immutable data structures. Using it is as simple as calling diff(left, right), where left and right are sequences of like-typed data to be compared; the result is an instance of Diff, a sequence of additions, deletions and no-change nodes representing each item in the left and right sequence.
