      Connections are leaking. Most likely related to https://github.com/mongodb/mongo-go-driver/commit/99bdb9492372cbf681e337926aca708bb3319076

      File x/mongo/driver/topology/server.go
      ```
      if isStreamingEnabled(s) && isStreamable(s) && !s.rttMonitor.started

      {             s.rttMonitor.connect()         }

      ```
      Here is a call to s.rttMonitor.started without a mutex. Which can lead to calling multiple connection methods.

      Detailed steps to reproduce the problem?

      Include full traceback, if possible

      Definition of done: what must be done to consider the task complete?

      The exact Go version used, with patch level:

      The exact version of the Go driver used:
