This will only push the problem one layer further, in the sense that the caller
of strdup would have to be duplicated as well. At that point, things start to
look a lot more like dlmopen rather than RTLD_DEEPBIND. However even with
dlmopen, separate mallocs may not be what users of this feature expect.
