If the behavior is x86-specific, it should be made x86-specific. z,
ppc, sparc, arm, etc should share the non-x86-specific code path. It's
weird to single out z here, this seems like the wrong way around.
Is the x86-specific behavior a problem in practice? No one seemed to
mind for the other targets.
