ASP.Net httpruntime executionTimeout not working (and yes debug=false)

Question

We just recently noticed that executionTimeout has stopped working on our website. It was definitely working ~last year ... hard to say when it stopped.

I came across this article 2 days ago when I had the same problem. I tried everything, it worked on my local machine but did not work on the production server. Today, I have a workaround that fixes the problem and would like to share. Microsoft seems to not apply timeout to IHttpAsyncHandler and I take advantage of that. On my system, I only have 1 handler that is time-consuming, so this solution works for me. My handler code looks like this:

public class Handler1 : IHttpAsyncHandler
{
    public bool IsReusable
    {
        get { return true; }
    }

    public void ProcessRequest(HttpContext context)
    { }

    public IAsyncResult BeginProcessRequest(HttpContext context, AsyncCallback cb, object extraData)
    {
        //My business logic is here

        AsynchOperation asynch = new AsynchOperation(cb, context, extraData);
        asynch.StartAsyncWork();
        return asynch;
    }

    public void EndProcessRequest(IAsyncResult result)
    { }
}

And my helper class:

class AsynchOperation : IAsyncResult
{
    private bool _completed;
    private Object _state;
    private AsyncCallback _callback;
    private HttpContext _context;

    bool IAsyncResult.IsCompleted { get { return _completed; } }
    WaitHandle IAsyncResult.AsyncWaitHandle { get { return null; } }
    Object IAsyncResult.AsyncState { get { return _state; } }
    bool IAsyncResult.CompletedSynchronously { get { return false; } }

    public AsynchOperation(AsyncCallback callback, HttpContext context, Object state)
    {
        _callback = callback;
        _context = context;
        _state = state;
        _completed = false;
    }

    public void StartAsyncWork()
    {
        _completed = true;
        _callback(this);
    }
}

In this approach, we actually do not do anything asynchronously. AsynchOperation is just a fake async task. All of my business logic is still executed on the main thread which does not change any behavior of the current code.
