This trunk patch should go into the 2.3 branch:
2005-07-13 Ulrich Drepper <drepper@redhat.com>
* nscd/nscd_helper.c: Add a few __builtin_expect.
* nscd/connections.c (send_ro_fd): Make sure BUF is aligned correctly.
* nscd/nscd_helper.c (wait_on_socket): New function.
(get_mapping): Use wait_on_socket instead of poll. The former handles
EINTR of poll correctly.
(__nscd_open_socket): Likewise.
(get_mapping): Make sure BUF is aligned correctly.
(get_mapping): Use munmap on correct pointer.
