Is this "doable"?
Maybe a little out of the box, but far simpler than the other
solutions so far if it'll do what you need:
egrep -Hn . <file1> <file2> | sort -t: -k2 | cut -d: -f3-
It'll work with any number of input files, wildcards, and you play
with the sort/cut parts to get more descriptive output if you want as
well, e.g:
egrep -Hn . <file1> <file2> ... <filen> | sort -t: -k2 | cut -d: -f1,3-

Does not work :(
it outputs first all the lines in file 1, followed by all the lines in
file2.
In my case the sort and the cut are not even needed.
Jon LaBadie's example worked like a charm
exec 5< .kshrc
exec 6< .profile
while read -u 5 one && read -u 6 two
do
echo $one
echo $two
done
