I'm unfortunately swamped with other things at the moment.

It should be fairly easy to to add a callback that returns either true or
false depending on whether the argument library should be registered.
The library could be described by an address range, and (possibly,
depending on platform) the path name for the library.  (On a few
platforms, the path name may always end up null, which would probably make
the facility useless there.)

If someone wants to submit a patch to dyn_load.c ...
