respawn: Adjust the oom score for the supervisor and bts/pcu, increase sleep
Make the script mostly unkillable due to OOM and make sure that the
process has a score of zero. Wait 10 seconds before re-launching.
The combination of ( && exec ) & appears to save one sub-process. The
script has been tested with bash and busybox's ash.
