-Subject: [PATCH] Fix doubly call of dlclose() in dlobj caching code
-
-When multiple dlobj_cache items point to the same dlobj, dlclose() may
-be called wrongly multiple times when these items are cleared, because
-we manage the dlobj_cache list as a flat list.  This results in a bad
-segfault we've seen in openal-soft, for example.
-
-For fixing this, we need the refcounting of dlobj itself.  But, in
-this case, we don't have to manage yet another list,  since dlopen()
-does a proper refcounting by itself.  That is, we can just call always
-dlopen() at each time a new function is assigned, and also call
-dlclose() for each released dlobj_cache item at cleanup.
