The testcase is invalid. As Paul said, you can use DF_1_NODELETE on libraries
that you don't want to unload ever, or if a library (libfoo) in this case
performs a cal to a function from libbar, it will have a dynamic dependency on
libbar through symbol resolution and thus would allow libbar to be unmapped
only when libfoo is about to go away too.
