OK. Sounds good. But, if you are going to signal completion via a
socket message to the main process, and have the main process ignore
SIGCHLD, why do you need the extra level of fork/exec? Oh... duh! So
that someone can send the message, since the editor won't! I've
written this down as 'to do' - thanks for the suggestion!
