There are legitimate applications where the value of data is low enough
and the load is high enough, that losing the database upon crash is ok.

I have mixed feelings about making it a mount option for reiser4 because
many users will not know what they do.  In the end though, I should just
sell the rope and advise but not control what people do with it.   If
someone writes it I will take a mount option patch to disable fsync iff
it comes with documentation that has a lot of warnings.
