I also mentioned in another recent thread what the sources to
glibc_post_upgrade look like:
pid =3D vfork ();
if (pid =3D=3D 0) {
execl ("/sbin/ldconfig", "/sbin/ldconfig", NULL);
_exit (1);
} else if (pid < 0) {
_exit (1);
}
if (waitpid (0, &status, 0) !=3D pid || !WIFEXITED (status)) {
_exit (1);
}
So if fork/waitpid communicate via sendmsg/recvmsg that would mean a lot
of linux programs would not work :(
