I'm trying this very simple benchmark that results in quite a lot of
AssemblyQualifiedName calls for each remoting call. My results are for a 5%
perf increase but my machine is too unsuited for benchmarking.

Can someone run it with and without the patch and report back the result?

using System;
using System.Threading;

public class Remote : MarshalByRefObject {
    public void Ping (Remote rem, object payload) { rem.Pong (payload); }
    public void Pong (object payload) { }

public class Driver {
    public static void Main()
        AppDomainSetup setup = new AppDomainSetup ();
        setup.ApplicationBase = ".";
        Console.WriteLine (AppDomain.CurrentDomain.FriendlyName);
        AppDomain newDomain = AppDomain.CreateDomain ("NewDomain", null,

        Remote rem = (Remote)newDomain.CreateInstanceAndUnwrap (typeof
(Remote).Assembly.FullName, "Remote");

        Remote local = new Remote ();
        for (int i = 0; i < 30000; ++i)
            rem.Ping (local, i);
