Me neither... though I can guess the window manager might change the  
size/position of the window, or the X system might be sending  
multiple events updating the window position.

Well, it certainly might be a bug and/or might just be a bit  
inefficient I suppose, or it might be correct behavior (eg. if the  
window manager is messing with the window).

i don't know, but I would suggest that TWO things need looking at ...

1. gnustep might be doing something wrong and/or inefficient ... is  
so, an analysis/ and fix if there is a problem would be good.
2. your application should be fixed to work when receiving different  
numbers of notifications ... as it's unsafe to make assumptions about  
the number of notifications received.
