Currently async generators have little documentation, we should add a best practices section for this in the docs to avoid common pitfalls.
Some of the things to be documented off top of my head:

• Recommend to manually close the generator instead of relying on the gc. (Most important)
• Avoid iterating and closing the same generator concurrently.
• Only create a generator when a loop is already running.

If anyone from the docs group is interested, that would be much appreciated.
