In which case, I propose this: mod_perl can save a copy of
@DynaLoader::dl_librefs, and then call perl_destruct.  After that it
can attempt to dlclose() them; the dlclose() calls will fail (silently)
if the modules are already unloaded, and do the right thing if they
weren't.

It's a bit of a messy hack, but how's that sound for coping with
fixed/unfixed versions of DynaLoader?
