It's Ubuntu hardy haron (2.6.24-16-generic).  It has rather old .996
xetex with texlive-2007, so I built it from repository today.

Another test on my installation shows that being enclosed in \fbox,
the enormously extended text protrudes to the right outside the box,
while the stretched one leaves some white space on the right.
