Ah. That makes sense. I have the feeling that lots of us are planning
for or actually using non-lazy loading as that lets the relocation
tables be marked read-only after startup (-z relro -z now in the gnu
linker).

That's a good point -- with lazy loading, if the other libraries aren't
even loaded until first used, then it seems unlikely that their init
sections are invoked before then.
