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.=
