Forgot about that question - pass. What happens anyway with >multiple interpreters? The exitlist functions will be called for every interpreter that shuts down via perl_destroy(). As long as the loader refcounts the dlopen()s and dlclose()s properly, I think we're ok. >Does dl_load_file() get called once per use/require'd .xs file per >interpreter instance?

Dups are normally avoided because modules only ever gets use-d once, but if somebody reloads a module, you could end up with dups. But that should be ok, since every duplicate means an additional dlopen() on the file, so the number of dlclose()s will match. Sarathy gsar@ActiveState.com
