Oh!

Thank you, Juergen, for providing facts!

I withdraw my ack on this patch.

I agree with all the complaints in the libc bugzilla and disegree with
glibc upstream.  I think this should be fixed in the libc.  Sadly the
libc bugzilla doesn't have a libc patch.

I would accept a workaround in libxenstore that does something similar
to what they do in Rust...

Ian.
