StackExchange.Redis Profiling Group all commands from set of threads together

Example

class ToyProfiler : IProfiler
{
    public ConcurrentDictionary<Thread, object> Contexts = new ConcurrentDictionary<Thread, object>();

    public object GetContext()
    {
        object ctx;
        if(!Contexts.TryGetValue(Thread.CurrentThread, out ctx)) ctx = null;

        return ctx;
    }
}


// ...

ConnectionMultiplexer conn = /* initialization */;
var profiler = new ToyProfiler();
var thisGroupContext = new object();

conn.RegisterProfiler(profiler);

var threads = new List<Thread>();

for (var i = 0; i < 16; i++)
{
    var db = conn.GetDatabase(i);

    var thread =
        new Thread(
            delegate()
            {
                var threadTasks = new List<Task>();

                for (var j = 0; j < 1000; j++)
                {
                    var task = db.StringSetAsync("" + j, "" + j);
                    threadTasks.Add(task);
                }

                Task.WaitAll(threadTasks.ToArray());
            }
        );

    profiler.Contexts[thread] = thisGroupContext;

    threads.Add(thread);
}

conn.BeginProfiling(thisGroupContext);

threads.ForEach(thread => thread.Start());
threads.ForEach(thread => thread.Join());

IEnumerable<IProfiledCommand> timings = conn.FinishProfiling(thisGroupContext);

At the end, timings will contain 16,000 IProfiledCommand objects - one for each command issued to redis.
