I'm 90% sure that (most of?) the leak your test exhibits is actually
caused by test itself: without your code you can see that the test
conses quite a bit itself. I'm thinking that when your code is loaded
it simply conses even more, and some things end up inopportunely
tenured -- and finally you run out of space.

Looking at the generation breakdown I'm thinking that (GC :GEN 2)
after MAP-ALLOCATED-OBJECTS should be sufficient to unkink this.

(What you are seeing is the result of an unfortunate combination of
issues in MAP-ALLOCATED-OBJECTS and the generational GC.)

Additionally, I would strongly suggest passing T as the third argument
to MAP-ALLOCATED-OBJECTS.

Oh, by the by: plain text messages are *strongly* preferred.
