> When 'truncate' is true for an Indexer's constructor, by a
> quirk of fate, it will always write a schema file named 
> "schema_1.json".  If the existing schema file is also named that
> (as it would be on successive truncating runs), the files will
> collide, resulting in either a clobber a crash depending on OS.
> The solution is to derive the name of the schema file from the
> name of the snapshot file.
