* nscd/nscd.h (prune_cache): Add fd argument to prototype.cvs/fedora-glibc-20060531T1322
* nscd/nscd.c (parse_opt): Read response from INVALIDATE request to make sure the database has been already invalidated. * nscd/cache.c (prune_cache): Add fd argument. Write response to fd after the cache has been invalidated. Use pthread_mutex_lock rather than pthread_mutex_trylock if fd != -1. * nscd/connections.c (invalidate_cache): Add fd argument, write response to fd if not calling prune_cache, pass fd to prune_cache. (handle_request): Adjust invalidate_cache caller. (nscd_run): Pass -1 as fd to prune_cache.
