As mentioned earlier, the immediate problem is that
org-adaptive-fill-function does not terminate (or at least takes too
long to terminate).

Now, one reason why this might happen here is that
adaptive-wrap-prefix-mode calls org-adaptive-fill-function everywhere,
so it might be called in places where it usually (i.e. when
adaptive-wrap-prefix-mode isn't in use) isn't triggered.
