If you loaded code read-only (-n) or demand-paged (-z), etext
is not necessarily on a R/W page.  You must round up to the next
protection unit of the machine in question and copy from there.
Note that the loader forces the start of data on -z and -n files to
be moved away from the text so that they don't share the same page
(or else part of text will be R/W or part of data will be R/O!!).

Also, are you saving the stack area.  I find that region is important
in most programs. :-)
