If I'm right and the error messages are caused by misaligned msync calls,
enabling that will just cause more of them because it will result in more
msync calls.  This problem is fixed in the new overview code in CURRENT.
But I don't think this would cause corruption; it should be harmless (and
just mean that overview isn't getting synced).
