But is that really what blocks it here? I try to use (sit-for 0) between 
the popup-menus but no redisplay happens there.

In the case where I am using this the buffer should be updated between 
the popup-menus. I think the user expect that to happen.

Why should redisplay be blocked between the popup-menus? Are the 
popup-menus active when the function choosen is called?

I consider this bug and I can see other bugs here that seems related. 
Though I do not know if these bugs are only related to the w32 port.
