Is there a block cache in between the hpkg virtual file system and the
user? If so, then this will amelioriate a lot of the performance
problems. (If not, there should be...)

In fact, given the kind access patterns that this kind of application
usually gets, it might make sense for the hpkg virtual file system to
bypass the block cache on the real filesystem --- there's no point
cacheing the compressed *and* uncompressed data.
