Try it out:

Erlang (BEAM) emulator version 5.6.1 [source] [smp:2]
[async-threads:0] [hipe] [kernel-poll:false]

Eshell V5.6.1  (abort with ^G)
1> self().
<0.31.0>
2> foo().
** exception error: undefined function shell_default:foo/0
3> self().
<0.34.0>

When you typo in the shell, that process dies and a new one is started.
