What about fragments? They cure the wasted space problem. Naturally it
would have been better to just do allocations of runs of small blocks,
like the ISC FFS does, but the fragment approach works almost equally
well, excep that it is much more complex.

There is some recent paper in some conference proceedings on how to make
even faster file systems.
