      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      Using an AsyncMongoClient across event loops is not supported. For example:

      client = AsyncMongoClient()
asyncio.run(client.server_info)
asyncio.run(client.server_info) # Undefined and erroneous behavior

      We should explicitly call out in the differences between Sync and Async PyMongo that AsyncMongoClients cannot be shared across threads or event loops.

      For context, Motor does not allow this either but users are often confused by that behavior.
