Something like that, yes.

Display a message about the error.

This means it exited successfully.  We could also maintain a data
structure where successfully-exiting threads will leave their success
status together with some id of the message they sent -- unlike a
thread that dies abruptly due to an error, a successful thread can
store the information in the data structure before exiting.
