In the long term, I'd like to spend my personal free time to decouple code like

Apart from that, it looks good to me,

This patch adds strategies which can be selected
by users in order to cache both incomplete ends of
compressed physical clusters as a complement of
in-place I/O in order to boost random read, but
it costs more memory than the in-place I/O only.
