GetAndLock not returning Locked status but timed out when doc is locked

Hi,
The Bug is in the GetAndLock mechanism that return op time out instread the proper error and in a propper time (it's about 4sec).

This is the code below:
var hosts = new List<Uri>

{ new Uri("http://Rois-MacBook-Pro.local:8091/pools") }

;
var config = new ClientConfiguration()

{ Servers = hosts }

;
var cluster = new Cluster(config);

var bucket = cluster.OpenBucket("workshop","test");

var sw = new Stopwatch();
sw.Start();
var res1 = bucket.GetWithLock<string>("roikatz",30);
sw.Stop();
Console.WriteLine("first op:

{0}, result: {1}", sw.ElapsedMilliseconds, res1.Status);
var sw1 = new Stopwatch();
sw1.Start();
var res2 = bucket.GetWithLock<string>("roikatz", 30);
sw1.Stop();
Console.WriteLine("second op: {0}

, result

{1}

", sw1.ElapsedMilliseconds, res2.Status);

And that is the output:
First op 8ms, result Success
Second op 4110ms, result OperationTimeout

In java this code return exception in about 2ms.
I suspect that is a bug in the SDK.

Thanks,
Roi
