  I don't really know how safe it is to live with this.  All the files
I've examined in lost+found (only a fraction of the files that have been
reconnected), I could identify as files that had been deleted after builds.
It may be harmless in principle, but with thousands of files reconnected,
it becomes very difficult to distinguish reconnected deleted files from other
reconnected files that one might actually want to salvage.  It's kind of like
living with a fire alarm that gives frequent false alarms but might signal a
real fire some day.  So I've turned off softdeps for now.
