What exactly is the issue? Have you traced the process with set -x? [embed set -x into each function in use to capture the flow across each subprocess...]
It could be, but not necessarily.

Well, if you must source and it must not kill the parent shell, it cannot use exit. Refactor the script so that it does not require it.

If you want to get really ugly, you could wrap the sourcing with something like:
Code:
exit() { return $1; }
. script
unset -f exit

Although that will not work if the exit calls occur within a function (the sourced function will return but the sourced script will continue executing).
