If there was a power failure at the wrong time you might have some left over bits and pieces. I suppose you could alleviate this to a great extent by having something like fsck for swap spaces which would zero them on bootup if there had been a "disorderly shutdown". If your information is so secret that this matters, though, you probably shouldn't be swapping at all! ----------------------------------------------------------------------- Pete Chown, email pc@skygate.co.uk, phone +44 (0) 181 680 8393, fax +44 (0) 181 688 8013, mobile +44 (0) 468 765 645, post 58 Foss Avenue, Croydon, CR0 4EU, England
