So, is there filesystem support for ExAll() such that the fs will "sort
and read file headers in a sequential (i.e. only-increasing or only-
decreasing block #'s) manner" when appropriate (ie. OFS or FFS)? This
would have the nice bonus of speeding up directory listings, no?
I guess what I meant was `is ExAll() atomic at the fs level, as well and
do the OFS and FFS take advantage of that?'?
