Comment (by karsten):

 Oh wow, that's quite some code there for preventing concurrent executions.

 Please don't hate me for this suggestion, but what do you think of making
 the periodic updater the normal mode of operation and getting rid of the
 lock file entirely?

 Want to take a look at #13600 and the branch there?  Note that it
 currently uses a lock file, but I could see us removing that.  Service
 operators would then be responsible for not starting two instances of the
 updater concurrently.  If there's no risk anymore that two cron runs get
 in each other's way, this seems like a reasonable assumption.

 Thoughts?
