I have not looked at what realy catches the problem, but I supposed it
would be the 

#ifdef DEBUG
	write_user_windows(); 
	...
#endif

call in syscall(). This is not cheap, and wasting it for every system 
call just to catch bogus programs is wrong, IMHO.

We should, however, make sure the exit syscall can succeed even if the return
path to userland is borked, and we should make sure such processes are 
killable.
