Almost. In PeekMessageW, the message should be removed before handling it

         if (msg.message & 0x80000000)
-->         handle_internal_message( msg.hwnd, msg.message, msg.wParam, 
msg.lParam );
             if (!(flags & PM_REMOVE))  /* have to remove it explicitly */
-->             peek_message( &msg, msg.hwnd, msg.message, msg.message, 

In 16bit SkiFree (again!), handle_internal_message()  leads to 
PostQuitMessage() & DefWindowProc(WM_NCDESTROY), which calls 
queue_cleanup_window in wineserver, which clears the queue of messages 
for the window. So, when peek_message is called again it removes 
WM_QUIT, which therfore never gets returned to the app.

Perhaps handling of internal messages should even be moved into
