@3vil,

One more thought.  You say, "You never know when your MB, CPU, PS" may
bite the dust.  Sure, but you also never know when your RAID controller
will bite the dust and start writing data blocks whenver it's supposed
to be reading from the RAID (yes, we had an Octel voice mailbox server
fail in just that way at MIT once).   And you never know when a hard
drive will fail.   So if you have those sorts of very high levels of
reliability requirements, then you will probably be disappointed with
any commodity hardware solution.   I can direct you to an IBM
salesperson who will be very happy to sell you an IBM mainframe,
however.

At the end of day, the best we can do about surviving unplanned crashes
in the absence of formal fsync() requests, is best efforts.  This is
true for all file systems, although it is true that the slowest file
systems may be more robust.   The patches is the best I can do without
completely sacrificing performance; but hey, if it's not good enough for
you, you're free to keep using ext3.
