I don't think that's likely to be a practical problem, and it's not likely it'd be worse than always doing writes. A lot of things are slower the first time you do them and you're still going to have to do the writes no matter what. --xHFwDpU9dbj6ez1V Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl3vi24ACgkQJNaLcl1U h9D/zwgAgJGg4Rzbjb/3neARAW2iuL6cC3Z2NQEUh8aJUuljcByF/iXTtlKuups0 bGOmzkA+eYmrW2wPZPoV88r4feU8A4ri9lzgR3G8cO5n3tAT3lvMiA0ENfYm99nk h+YwnKi6WIhhQw4BNNdIfmqr+UfNCUIKLwpmdo2hqm8ALwp/2O9Ge1tpdqVMWfk4 bV+sqZQW/yxKYYl2vBz9YVw2WGQV7me/vK4fPbxcjUe1nIDJ2MSR2ZZL3Io5RRZ5 f/V3zG3Ao8ak6Hgg8HaAmZKGsJqtSn1AFwm//zV8BNDHkHC745uTnvIs702ytDgl o4pdZZNbPIMmyOtLJtueNJUHBCIwsw== =S22J -----END PGP SIGNATURE----- --xHFwDpU9dbj6ez1V--
