   I tried searching the Internet for such issues, but couldn't find
   any. What do you recall as being the loader problem?  The "extern"
   part?  Or use of a null string for termination?

OK, found it.  "How to Write Shared Libraries" by Ulrich Drepper,
version 4.0, section 2.4.3 "Arrays of Data Pointers".  See also the
programs in Appendix B.

I think the problem is (relatively) high constant ldso overhead for a
rarely-used facility.  However, i'm not sure if those concerns are
relevant in this context.  If not, sorry for the noise!
