      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?

      We've just had to roll back our mongodb driver from v6.4.0 to v6.3.0 because of a memory leak.

      Possibly related to https://github.com/mongodb/node-mongodb-native/pull/3948 

      Specifically may be related to the Connection.aborted promise?

      I took a heap snapshot, which shows >500MB (72%) of our heap spent on Connection objects, and Promises (see attached screenshots)

      I sadly can't upload the heap because of the size, and because it will contain customer data, but I'm happy to poke around in it if it's helpful?
