First emacs is still a rather small executable, there are much larger
ones around.

That large xattrs tend to be out of line on a separate block and that would cost 
an additional seek. It would be unlikely to be continuous to the rest of the file 
data and thus even be worse than the SHDR which is at least likely to be
served from the same track buffer as the executable.
