I see. A little question on the importanceness of solving this right up
front: is it possible to change the fibration policy of a mounted and active
file system? Does such a change affect the repacker (as in: swapping the
fibration policy causes the repacker to start shuffling things around
according to the new policy)? If that's the case, then I guess there's some
wiggle room for imperfection...

(in fact, on second thought, my request wouldn't necessarily cause the best
performance to happen. Norton Defrag used to have a "sort by type" option
ca. 1994, and I remember that on my PC, it didn't give the best
performance). 

Just out of curiosity, is it possible to create a fibration policy based on 
atime/mtime/ctime?
