Does sqlite pass its tests on GNU/Hurd?

Does it help if you set ‘settings.fsyncMetadata = false’ in the daemon?
As a stop-gap, we could add a command-line option if that helps.

The “synchronous = normal” mode translates to ‘fsync’ calls, right?  If
you rpctrace sqlite3, do you see ‘file_sync’ calls failing?

My 2¢!
