dist_utils: Eliminate crash when list_to_existing_atom/1 fails
In the following scenario list_to_existing_atom/1 may crash during handshake: Start a node in one window: erl -sname adam@localhost Start another node in another window: erl -sname bertil In this node, ping the first node (use the actual hostname in the command): net:ping(adam@hostname). There will be an error report similar to: =ERROR REPORT==== 27-May-2010::15:03:14 === Error in process <0.40.0> on node 'bertil@hostname' with exit value: {badarg,[{erlang,list_to_existing_atom, ["adam@localhost"]},{dist_util,recv_challenge,1},{dist_util,handshake_we_started,1}]} Eliminate the crash and the error report by catching the call to list_to_existing_atom/1 and do a clean shutdown if it fails.
