Willy Tarreau	ee17b97eea	DOC: scheduler: add a diagram showing the different queues and their usages ... The scheduler has become complex over time and the latest updates were a good opportunity to document it. This diagram shows the time-based wait queue(s), the priority-based run queue(s), and the class-based tasklet queues, trying to emphasize what is local-only and what is shared between threads. The diagram is provided in .fig, .svg, .png, and .pdf.	2021-02-26 17:49:37 +01:00
