The following test program:

#include <libvisual/libvisual.h>

int main (int argc, char **argv)
{
        VisPluginRef *ref1;
        VisPluginData *plug1;
        VisPluginData *plug2;

        visual_init (&argc, &argv);

        ref1 = visual_plugin_find (visual_plugin_get_registry (),
"oinksie");

        printf ("%p\n", ref1);

        plug1 = visual_plugin_load (ref1);
        plug2 = visual_plugin_load (ref1);

        printf ("plug: %p\n", plug1);

        visual_plugin_realize (plug1);
        visual_plugin_realize (plug2);

        visual_plugin_unload (plug1);
        visual_plugin_unload (plug2);

        return 0;
}



Works perfectly, what dlopen seems to do here, is when a library gets
opened twice, generate one fake handle. and close the library for real
if the last handle is being dlclosed(). Can you show me your code
that does not work, or make it possible for me to test.

If it seems that dlopen is indeed different on different systems, I can
introduce an easy hack into the plugin loader that keeps track on the
real handle. But I really think this is NOT needed...
