Once we had called log_free_all(), anything that tried to log a message (like a failed tor_assert()) would fail like this: 1. The logging call eventually invokes the _log() function. 2. _log() calls tor_mutex_lock(log_mutex). 3. tor_mutex_lock(m) calls tor_assert(m). 4. Since we freed the log_mutex, tor_assert() fails, and tries to log its failure. 5. GOTO 1. Now we allocate the mutex statically, and never destroy it on shutdown. Bugfix on 0.2.0.16-alpha, which introduced the log mutex. This bug was found by Matt Edman.9d118277
