Hmm, what happens if applications keep dirtying so much data you miss
your 17minute deadline?
+ lots of memory
+ tweaked settings of kflushd (only write data older than 10 years)
+ just not using sync/fsync except during shutdown
+ find / | xargs cat
...is ramback, right? Should have same performance, and you can still
read/write during that 17+17 minutes.
Ok, find | xargs might be slower... but we probably want to fix that
It has big advantage: if you only tell kflushd to hold up writes for
an hour, you loose a little in performance and gain a lot in
(If ext2+tweaks is slower than ramback, we have a bug to fix, I'm
