That ought to happen automatically when the program calls exit. Another
way to set up a cleanup function is to use atexit().

One thing that might be causing your problem is that Exim frequently calls
exec() which doesn't invoke the usual exit cleanups. If you want some
cleanup to occur in this situation then you're out of luck: you'll have to
do it eagerly rather than lazily. This shouldn't cause much extra work
since Exim's processes are usually short-lived.
