Because there is an atexit() handler that a) needs to be active and b) 
does evil[tm] things that are only partially set up at the point where 
this string is output and then _exit()ed.

And nothing whatever to do with the fact that someone couldn't be 
bothered (or was too stressed to) rearrange things so that atexit() is 
called slightly later to enable exit() to be used at that point. Oh no, 
nothing like that at all...
