open(2) and O_NOATIME

[Jeremy Chadwick]

I've recently been reading about Linux's O_NOATIME flag to open(2), and
I'm curious why we haven't implemented this.  There seem to be a lot of
good reasons to implement such a thing.

Chances are it's due to lack of time/interest, which is expected, but I
was wondering if there were other reasons.

I realise mount's noatime trumps this, but there are lots of scenarios
where atime is desired as a default, but disabled in specific cases.
