sh:

for i in whatever
do
...
done &

(just stick an & after the done)

I tried various ways to do this in csh, including putting the whole thing in
a subshell explicitly and putting \'s at the end of every line, or
embedding control-J's in the line, but it wouldn't work.  There might be
a simple way, but who cares?  Use sh anyway; its behavior is much more
predictable and reliable than csh's, especially for shell scripts.
