Comment (by teor):

 We do get the tor logs, but we're not propagating the USR1 and ABRT
 signals from stem to tor:
 {{{
 Apr 22 03:32:30.000 [notice] Monitored process 20402 is dead.
 Apr 22 03:32:30.000 [notice] Owning controller process has vanished --
 exiting now.
 Apr 22 03:32:30.000 [notice] Catching signal TERM, exiting cleanly.
 }}}

 I'll open another child of #29437.
