When a dynamic extension is being remade, it is unloaded by calling
unload_file.  The latter looks up its argument in a linked list of
loaded objects.  Now, unload_file is called with file->name as its
argument; is it 100% sure that this string will be identical to what
was used in load_file?  IOW, do we never change relative file names to
absolute ones (or vice versa), mirror backslashes to forward slashes,
or do any other transformations that produce a different string which
points to the same file?  If we can do such transformations, unloading
will be unreliable.
