      Leads to timeouts due to hanging DisposableMongoClient.Dispose(). Was not able to reproduce locally.
      From brief investigation two flavors where observed:

      • Execution blocked at monitorCancellationTokenSource.Cancel(); in ServerMonitor.Dispose()
      • Execution blocked at _cancellationTokenSource.Cancel(); in RoundTripTimeMonitor.Dispose()
