Ehm, well:

        case "$i" in
                        # Source shell script for speed.
                                trap - INT QUIT TSTP
                                set start
                                . $i

.. *.sh script are already sourced in a subshell.

"exit" is survived:

$ ash -c '( exit 1 ); echo bar'

.. and so is "set -e":

$ ash -c '( set -e; skjdhkshds; echo foo ); echo bar'
ash: skjdhkshds: not found
