it does not help, however it looks that the patch makes anyway sense 
because it is fragile to get a NSRect back from a proxy? (I suppose this 
is true for all structs then?)

Actuall, if I put a NSLog in getWinRect, it does't even get called (and 
it shouldn't, if there are no outstanding file ops) and yet GWorkspace 
hangs.

So perhaps I have a more general problem: with current base/gui/libobjc2 
I get a hang, but it is not that specific function returning a rect.

I made rectForFileOpWindow return a NSZeroRect directly, to cut out that 
source of trouble for now, yet I still have the problem.

Can actually someone reproduce this or does it happen only to me?
