*I* don't understand what it is supposed to fix. Using Winsight
was a rather brainless attempt to see what is happening under
Windows.

Now I think I see : this can only be useful if EndDialog is called from
another thread, right ? If yes, you really *should* mention this in the
remark before the code. No need to be mysterious IMHO.

Anyway, I tested your patch with a thread I launched before the
DialogBox call; after 15" of sleep the thread is calling EndDialog.
To add fun I added a WM_NULL handler in the dialog procedure
to display a  MessageBox; under Windows the MessageBox does not fire,
under Wine with your patch, it does (test app available)
So probably Windows does not do it this way (or the WM_NULL message is 
filtered). It probably does not matter much, granted.
