It _should_ work, and I don't see a reason that it wouldn't, but
just in case, add a 10 second timer to make tor die with an
assertion failure if it's supposed to exit but it doesn't.
This function was never about 'finishing' the event loop, but rather
about making sure that the code outside the event loop would be run
at least once.
Sometimes when we call exit(), it's because the process is
completely hopeless: openssl has a broken AES-CTR implementation, or
the clock is in the 1960s, or something like that.
But sometimes, we should return cleanly from tor_main() instead, so
that embedders can keep embedding us and start another Tor process.
I've gone through all the exit() and _exit() calls to annotate them
with "exit ok" or "XXXX bad exit" -- the next step will be to fix
the bad exit()s.
First step towards 23848.
Skip test_config_include_no_permission() when running as root, because
it will get an unexpected success from config_get_lines_include().
This affects some continuous integration setups. Fixes bug 23758.
When we added HTTPTunnelPort, the answer that we give when you try
to use your SOCKSPort as an HTTP proxy became wrong. Now we explain
that Tor sorta _is_ an HTTP proxy, but a SOCKSPort isn't.
I have left the status line the same, in case anything is depending
on it. I have removed the extra padding for Internet Explorer,
since the message is well over 512 bytes without it.
Fixes bug 23678; bugfix on 0.3.2.1-alpha.
Because our monotonic time interface doesn't play well with value set to 0,
always initialize to now() the scheduler_last_run at init() of the KIST
scheduler.

When a channel is scheduled and flush cells returns 0 that is no cells to
flush, we flag it back in waiting for cells so it doesn't get stuck in a
possible infinite loop.
It has been observed on moria1 where a closed channel end up in the scheduler
where the flush process returned 0 cells but it was ultimately kept in the
scheduling loop forever. We suspect that this is due to a more deeper problem
in tor where the channel_more_to_flush() is actually looking at the wrong
queue and was returning 1 for an empty channel thus putting the channel in the
"Case 4" of the scheduler which is to go back in pending state thus
re-considered at the next iteration.
This is a fix that allows the KIST scheduler to recover properly from a not
entirelly diagnosed problem in tor.

When we added single_conn_free_bytes(), we cleared the outbuf on a
connection without setting outbuf_flushlen() to 0. This could cause
an assertion failure later on in flush_buf().
Fixes bug 23690; bugfix on 0.2.6.1-alpha.
This caused a BUG log when we noticed that the circuit had no
channel. The likeliest culprit for exposing that behavior is
d769cab3e5, where we made circuit_mark_for_close() NULL out
the n_chan and p_chan fields of the circuit.
Fixes bug 8185; bugfix on 0.2.5.4-alpha, I think.
My current theory is that this is just a marked circuit that hasn't
closed yet, but let's gather more information in case that theory is
wrong.
Diagnostic for 8185.
