If we consider that it is not safe to unload a library (e.g. loaded by
VLC, hence module_unneed() not calling dlclose()), then nothing is

JNI provides a function to load a library (System.loadLibrary()) but
AFAIK there is nothing to unload.

It seems that it's more or less the same for Python CTypes.
