 When cfgmgr couldn't access config file,

 ... instead of waiting for this to timeout, I pressed Ctrl-C, resulting
 in:

 {{{

 During handling of the above exception, another exception occurred:

   File "/home/reed/opt/bind10/sbin/bind10", line 838, in main

 }}}

 What happened in the above is that everything was exited except msgq, it
 was left running so next time starting bind10 failed due to

 {{{
 [bind10] Checking for already running b10-msgq
 [bind10] Error on startup: b10-msgq already running, or socket file not
 cleaned , cannot start
 }}}

 If I do let it timeout on its own, bind10 just exit everything including
 b10-msgq.

 (Please ignore the permission denied in the above output; that is
 unrelated to my problem.)

 Also why SIGKILL?
