This test case makes memory grow quickly. It works fine if the instance
delegate (cls.Run) is replaced by a delegate to a static method.

using System;
using System.Runtime.InteropServices;

namespace DelegateTest
    class MainClass
        public static void Main (string[] args)
            MainClass cls = new MainClass ();
            while (true) {
                uint id = g_timeout_add (500, cls.Run, IntPtr.Zero);
                g_source_remove (id);

        bool Run ()
            return false;

        static extern void g_source_remove (uint id);

        static extern uint g_timeout_add (uint id, Func<bool> function, IntPtr
