pthread_getstacksize indicates 8,388,608 bytes. It doesn't seem 
excessive, but the 32-bit build does find that too big. If I try to set 
stack size to that value with pthread_setstacksize, indeed the thread 
fails. So it's not that you need to call pthread_setstacksize, you need 
to call it with a smaller value. -- Andrei
