That is NOT the case. This works as it should for worker threads!

Please, show me what in my code would not work!

// Called on main thread to terminate OtherCWinThread (a CWinThread object, UI thread)

OtherCWinThread.PostThreadMessage(WM_QUIT, 0, 0);

while (1)
{
    DWORD dwWaitRet = ::MsgWaitForMultipleObjects(1, &OtherCWinThread.m_hThread, FALSE, INFINITE, QS_ALLEVENTS);

    if (dwWaitRet != WAIT_OBJECT_0 + 1)
        break;

    MSG msg;
    while ( ::PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE)) 
    { 
        AfxGetApp()-> PumpMessage(); 
    } 
}
