Comment (by opara):

 Hi, just wanted to leave a few comments:

 (1) The function 'tor_run_thread_cleanup_fn()' is never run. I checked
 this by adding the following and checking that they never execute (added
 the call to system since I didn't check if the logging subsystem will
 still log at this point of the shutdown procedure).

 {{{
 tor_run_thread_cleanup_fn(void)
 {
   log_warn(LD_OR, "HERE");
   system("touch /tmp/abc");
   if (thread_cleanup_fn)
     thread_cleanup_fn();
 }
 }}}

 (2) The code comments still say "func should not return, but rather should
 call spawn_exit", but if you do this, then "tor_run_thread_cleanup_fn()"
 would be run twice (once in spawn_exit and once in tor_pthread_helper_fn).
