deadlock + transaction timeout

Hej, napisalem ponizszy przyklad sztucznie tworzacy deadlock

using System;
using System.Threading;
using System.Transactions;

namespace SampleDeadlock
{
    class Program
    {
        private static object lockerA = new object();
        private static object lockerB = new object();

        static void Main(string[] args)
        {
            Thread transaction1 = new Thread(new ThreadStart(Transaction1));
            Thread transaction2 = new Thread(new ThreadStart(Transaction2));

            transaction1.Start();
            transaction2.Start();

            transaction1.Join();
            transaction2.Join();

            Console.WriteLine("done");
            Console.ReadKey();
        }

        private static void Transaction1()
        {
            try
            {
                using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew))
                {
                    ModifyResourceA("T1");
                    scope.Complete();
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
        }

        private static void Transaction2()
        {
            try
            {
                using (TransactionScope scope = new TransactionScope(TransactionScopeOption.RequiresNew))
                {
                    ModifyResourceB("T2");
                    scope.Complete();
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
        }

        private static void ModifyResourceA(string transactionId)
        {
            Console.WriteLine(transactionId + " attempt to lock RA");
            lock(lockerA)
            {
                Console.WriteLine(transactionId + " is modifying RA");
                Thread.Sleep(1000);
                ModifyResourceB(transactionId);
            }
        }

        private static void ModifyResourceB(string transactionId)
        {
            Console.WriteLine(transactionId + " attempt to lock RB");
            lock (lockerB)
            {
                Console.WriteLine(transactionId + " is modifying RB");
                Thread.Sleep(500);
                ModifyResourceA(transactionId);
            }
        }
    }
}

maksymalny czas zakonczenia transakcji ustawiony w app.config to 5 sekund

<configuration> <system.transactions> <defaultsettings timeout="00:00:05" /> </system.transactions> </configuration>

Pomimo tego po 10 minutach dalej program wisi na deadlock'u. Wydruk z consoli:

T2 attempt to lock RB
T2 is modifying RB
T1 attempt to lock RA
T1 is modifying RA
T2 attempt to lock RA
T1 attempt to lock RB

Czemu transakcje nie przerywaja swojego wykonywania i jak je do tego zmusic ?
