Subject: Don't recurse in advertise() on writev(2) error, just write(2).
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/390acba226dd2bce2335ffed2318a79d554861da?hp=390acba226dd2bce2335ffed2318a79d554861da

Don't recurse in advertise() on writev(2) error, just write(2).
Some errors, e.g. EPIPE, cause the advise()'s call to another
advertise() to fail again, ad segvinitum when stack busts.  Instead,
snprintf(3) and write(2) that single string, ignoring any error.
