DumpRenderTree used to store font resources in a __DATA section, and to activate them from memory. We stopped doing that to work around <rdar://problem/6698023>.
That bug got fixed, but there is no harm in just keeping the current behavior, and that's certainly easier that restoring and modernizing the code to activate from memory.
