-[NSPersistentStore metadataForPersistentStoreOfType:URL:error:] failed again today while testing my app.  This time, the stuff it logged to the console was different than I recall seeing ever before…

CoreData: error: (3850) I/O error for database at /path/to/Document.sql.  SQLite error code:3850, 'not an error' errno:9

“not an error”!  Indeed, immediately after it returned nil, my reverse-engineered “black hat” branch kicked in, queried the document/database using the sqlite.c library, and got all of the metadata with no problem.

Weird.
