You're ignoring reality. Your definition of "quality software" is PURE SH*T. Look at that laptop disk spinup issue. Look at the performance issue. Look at something as nebulous as "usability". If adding fsync's makes software unusable (and it does), then you shouldn't call that "quality software". Alan, just please face that reality, and think about it for a moment. If fsync() was instantaneous, this discussion wouldn't exist. But read the thread. We're talking 3-5s under NORMAL load, with peaks of minutes.
