I believe that there is (or at least was) already dl_iterate_phdr,
and that for some reason this was added to get the list of classes
without actually loading
the object file?  If that path still exists, its perhaps possible this
series of issues, is people using this API,
and calling frameworkClasses without causing the loading shared object.
