Note that 'mysqladmin shutdown' just sends a signal to mysqld to close
done;  It will not wait until mysqld is completely shut down.

If you want to do this, you should monitor the .pid file until it
disappears or just add the table checking to the end of safe_mysqld.

Matt, could you look at adding code in 'mysqladmin shutdown' to
wait until the pid file is removed?
