It looks right per the exim docs. However, the local_scan facilities
are not something the exim testsuite exercises; quite possibly something
has been broken. They're also not something I've ever explored.

I doubt the permanent-pool is broken as a general thing; all
sorts of odd things would be visible in general operation.


There's a couple a memory-related debug facilities it might be
possible for you to try:

- a main-section option "debug_store", boolean.
Set true to add checks on whether any memory being used
by an active exim $variable is covered by a blob being
freed.

- run under the test-harness; freed memory is overwritten
by a distinctive pattern.
