bug10449: a dying owning controller makes Tor exit immediately

If you want a slow shutdown, send SIGNAL SHUTDOWN.

(Why not just have the default be SIGNAL QUIT? Because this case should only happen when an owning controller has crashed, and a crashed controller won't be able to give the user any "tor is shutting down" feedback, and so the user gets confused for a while. See bug 10449 for more info) --- changes/bug10449 | 8 ++++++++ src/or/control.c | 17 ++++------------- 2 files changed, 12 insertions(+), 13 deletions(-)
