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.
