* ext/socket/socket.c (bsock_do_not_rev_lookup_set): should not be
allowed when $SAFE > 3. * eval.c (rb_thread_ready): THREAD_TO_KILL threads should not turn into THREAD_RUNNABLE on wakeup. * eval.c (rb_thread_list): THREAD_TO_KILL threads should be in the list. * eval.c (thgroup_list): ditto; by moving gid clearance from rb_thread_cleanup(). * dir.c (fnmatch): "*/bar" (with FNM_PATHNAME flag) does not match "foo/bar". * io.c (read_all): files on /proc filesystem with zero stat size, may have contents. * ext/socket/socket.c (tcp_s_gethostbyname): refactored. * ext/socket/socket.c (sock_s_gethostbyname): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@2271 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
