Great TODO updates from Tom:
< Currently SIGTERM of a backend can lead to lock table corruption.
> Lock table corruption following SIGTERM of an individual backend
> has been reported in 8.0. A possible cause was fixed in 8.1, but
> it is unknown whether other problems exist. This item mostly
> requires additional testing rather than of writing any new code.
