Yeah, we never call dlclose on the returned shared object handle, so reloading a module will only increment the handle's reference count. It might make sense to support reloading in some way (by having unload-feature eventually call dlclose), but it's not trivial: we need to be careful to invalidate all references to affected module functions before calling dlclose.
