Comment (by dcf):

 Strangely enough, if I add `-log meek-client-torbrowser.log` after `meek-
 client-torbrowser` in Browser/TorBrowser/Data/Tor/torrc-defaults, then it
 kills the process cleanly. Adding the logging lines just causes a few log
 messages about killing the two child processes:
 {{{
 2016/09/14 19:31:27 sig terminated
 2016/09/14 19:31:27 sending signal terminated to PID 4885
 2016/09/14 19:31:27 killing PID 4885
 2016/09/14 19:31:27 killing PID 4856
 }}}
 Maybe related to #15125.
