Except that the process *does* exit (note that my shell displays the
pid in the prompt, but I've added self() calls to be clear):

Erlang/OTP 17 [erts-6.4.1.2] [source-73fc7ca] [64-bit] [smp:12:12]
[async-threads:10] [hipe] [kernel-poll:false]

Eshell V6.4.1.2  (abort with ^G)

undefined
<0.33.0> 3> get().
[{a,1}]
<0.33.0> 4> 1/0.
** exception error: an error occurred when evaluating an arithmetic expression
     in operator  '/'/2

[{a,1}]
