a) ext3 and xfs are logging filesystems, so the problem with 
asynchronous metadata updates possibly corrupting the filesystem on a 
crash doesn't arise.
b) asynchronous metadata updates wouldn't have any performance benefit

c) please cut down your quotes, and write your answers below or between 
the quoted text, instead of the outlook text-above-fullquote style. thanks.
