On OSX default connection pool hangs when doing bulk async/await ops

//first add the appropriate using statements to the class header:

using Couchbase.IO;

using Couchbase.IO.Services;

....

// later create a client configuration and pass into the ClusterHelper.Initialize or the Cluster ctor:

 var config = new ClientConfiguration

 {

        Servers = new List<Uri> {new Uri("http://localhost:8091/")},

 };

 config.ConnectionPoolCreator = ConnectionPoolFactory.GetFactory<ConnectionPool<MultiplexingConnection>>();

 config.IOServiceCreator = IOServiceFactory.GetFactory<MultiplexingIOService>();

 ClusterHelper.Initialize(config);
