Yes, this subject is a good flamewar catalyst. Crashes are not limited to 
hardware. With a RAID controller with write-back cache (backed) the 'sync' 
mounted FS is not costly at all. I don't have it right now, but still won't 
mount my FSes 'async' (and MTA requires 'sync'). The machine has been in 
near-crash states before (I accidentally exhausted all physical and swap 
memory a long while ago).
