Comment(by rransom):

 In `control_ports_write_to_file` in
 [https://gitweb.torproject.org/nickm/tor.git/commitdiff/1a9a29e73efa1771f772e5a411da15d643c56afe
 commit 1a9a29e73efa1771f772e5a411da15d643c56afe], you're joining strings
 using the empty string as a separator; you want to use `"\n"` instead.

 Also, I don't think you want to log the multi-line string that you're
 about to write to the file at level notice.

 Also, you should free the smartlist when you're done with it.

 In `tor_cleanup`, the ‘Remove our pid file.’ comment is misplaced; you
 could move and expand it or nuke it.

 In
 [https://gitweb.torproject.org/nickm/tor.git/commitdiff/da3f3a81e276812f49a66416576e85779fbd6580
 commit da3f3a81e276812f49a66416576e85779fbd6580],
 ControlPortFileGroupReadable deserves a changes/ entry.

 Other than that, looks good.
