we cannot hook system DLL unless we really want to "play dirty" with the 
operating system (eg. use detours). If we try to do that, we would probably 
lose testers not willing to mess with their machines (eg. because these 
machines might actually belong to someone else, like employer; or because 
these machines are used to other tasks where more conventional behaviour is 
desired).

it's actually pretty simple, that is: "this is how these things are usually 
done in Win32 world - find the window and send WM_CLOSE message to it". 
Someone more experienced could simplify my code, but I believe that it's "good 
enough". Hooking DLLs is much more complex and affects whole system.

Unfortunatelly, this is not *nix world and different rules apply

But, we could indeed (quite easily) read text content of those pesky message 
boxes before closing them and put that content in stdout or stderr (bjam ones, 
not the ones of the failing process) - is there desire for such feature?
