Are non multi threaded applications considered well written ?
listener = socket(...);
bind(listener, ...);
listen(fd, 10000);
Loop 1 10
if (fork() == 0)
do_accept(listener)
Now if a child does a close(listener), or is killed, you propose that it
does an implicit shutdown() and all other children no longer can
accept() ?
Surely you did not gave all details on how it is really working.
