These issues have been discussed a few times, but not with any results as 
exciting as you might hope for.  One which was mentioned was using 
fdatasync() instead of fsync().

One thing that has occurred to me (which has not been previously discussed as 
far as I recall) is the possibility for using sync() instead of fsync() if 
you can accumulate a number of files (and therefore replace many fsync()'s 
with one sync() ).

If you send email to me or to a mailing list that I use which has >4 lines
of legalistic junk at the end then you are specifically authorizing me to do
whatever I wish with the message and all other messages from your domain, by
posting the message you agree that your long legalistic sig is void.
