A programmer must never say "certainly" before testing.
Try this...

Code:

---

    theApp.PostLambda([=]()
    {
      AfxMessageBox(_T("There was an old man of Five Rocks"));
      theApp.PostLambda([=]()
      {
          AfxMessageBox(_T("Who shut his wife up in a box."));
          theApp.PostLambda([=]()
          {
            AfxMessageBox(_T("When she said \"Let me out!\""));
            theApp.PostLambda([=]()
            {
                AfxMessageBox(_T("He replied \"With no doubt"));
                theApp.PostLambda([=]()
                {
                  AfxMessageBox(_T("You will spend all your life in that box.\""));
                });
            });
          });
      });
    });

---

...and see that no deadlock occurs.
But of course, me either don't say "certainly" in a gazillion of other possible cases. :)
