That's going to be kind of painful for the current GNOME userspace, we
sadly emit a lot of crap at bootup =/  (I'm slowly trying to trim it,
but...it's slow going)

And bootup is pretty much exactly the point at which you don't want a
process stuck in fdatasync() right after everything has queued a lot of
writes to the journal becuase of atime updates...

Isn't after 10 minutes good enough?  

This should probably be tuned to stuff like the ext4 commit interval.
