Imported functions do not keep a backlink to the libraries they come
from, so libraries would get unloaded while you still keep references
to their functions. I didn't consider unloading libraries as a
priority, so didn't include this backlink. The loaded table does
double duty as a way to keep library objects alive and as a cache to
keep from searching for the library more than once.

Forcing the unloading of a library the way you are doing should not
cause problems if you keep from calling any function from that
library, though. Can you show an example of the code that is causing
