And two more commits on top of it, to workaround issues with this clone() call on niche architectures. First, there is no clone() on ia64, but there is a __clone2() with a slightly different semantics instead. The latter is documented but no prototype is provided by glibc. Second, it crashes with SIGBUS on hppa which is not happy with the child_stack address. When using obscure functions like clone(), issues are popping up like mushrooms after the rain. -- ldv
