Aren't Queue calls Isolated? I have a simple queue function which starts by logging the number of messages logged so far. The Logger is a simple ES6 module I wrote by myself. If queue calls were isolated (by creating a V8 isolate for each call), then the logged number of messages should always be Zero. But it's not. It's always increasing which means all queue calls are being made within the same running environment. IS it how it's designed? I was under impression all Workers calls create a new V8 isolate and there is no shared data/memory between the calls.
