Comment (by simonmar):

 >  Unload (dlclose) the dummy shared object. This will also unload shared
 objects that are to be unloaded (unless they are still referenced by other
 still loaded libraries).

 Note that (as discussed in D1631) this is dangerous because there might
 still be references to the old code from the heap.
