Here is one more for you:
Suppose we grow the last fragment/tail/whatever. Do you copy the
data out of that shared block? If so, how do you update buffer_heads in
pages that cover the relocated data? (Same goes for reiserfs, if they are
doing something similar). BTW, our implementation of UFS is fucked up in
that respect, so variant from there will not work.
