That's basically what I did, but the C shared library still seems to be loaded in the memory and pmap still shows that it's there.

"unrequire" successfully removes the Lua visible references to a C shared library, but it doesn't actually unload it from the memory. From what I can tell, ll_unloadlib() is only called when the userdata with the shared library handle is GC'ed ( which usually is when the Lua state is closed, since the userdata is in the registry )
