History
Tijl Coosemans f236378b54 Set the return address for stack entry points to zero. 
Stack unwinders treat zero as a stop condition.  The value on the stack can
be non-zero because thread stacks may be arbitrary memory provided via
pthread_attr_setstack(3) or may be recycled from previous threads.
