In this case, that's unnecessary. Your login is handled by the currently
running sshd process which won't be stopped by init.d/sshd stop. But
before you log out, make sure you can still log in from another
terminal.

The problem Sasha describes is one to worry about though. I've done it
with iptables and ifconfig before, although I'm sure there are plenty of
other ways.
