TBH I'm not even sure dlclose() is called at all since I wasn't able to track
this call down through all the handlers, destructors and so on in 5 min I spent on this..
Additionally there's no restriction on this once safe_mode is gone, so
anybody could load any C extension - while that can be fixed by
That's right, disabling it is not a problem.
