Comment(by aagbsn):

 Here are some options I've thought of:

 1. Make main thread aware of the child thread state (via signals) and exit
 when appropriate.
   - pro: Could be implemented with a custom signal/handler and os.kill()
 fairly trivially.
   - con: not generic; may require programs that use TorCtl to implement
 signal handling.

 2. Allow BwAuthority to die when TorCtl fails. This has been the default
 behavior.
   - pro: current behavior, requires no change
   - con: BwAuthority dies.

 3. Do not exit BwAuthority when bwauthority_child is killed with SIGTERM.
 (Restart child)
   - pro: trivial to implement
   - con: makes bwauthority a pain to kill, though could modify run_scan.sh
 to use kill -9
