Yes, I think this is an improvement.  It is an API change
however.  I think we can argue that it is a compatible change,
since .dlloader_init was undocumented before, and calling it
a second time needs to be a no-op (we need to fix preopen.c!).
That still means both CURRENT and AGE of libltdl need a bump.
Further, NEWS needs an entry, the patch should be tested on
Darwin and on some system with only the preloader enabled
(probably ok to just force this somewhere).

Ideally, we should have a test that adds a user-written loader
and exercises that, to ensure our documentation is accurate, too.
(This loader can just fake all operations and never look at the
file system.)

I can help with stuff you're not volunteering for.

Thanks,
Ralf
