    Well... when I saw this my immediate reaction was "oh no, yet another
    decompressor for the kernel". We have five of these things already.
    Do we really need a sixth?

    My feeling is that we should have:
    - one decompressor which is the fastest
    - one decompressor for the highest compression ratio
    - one popular decompressor (eg conventional gzip)

    And if we have a replacement one for one of these, then it should do
    exactly that: replace it. I realise that various architectures will
    behave differently, so we should really be looking at numbers across
    several arches.

    Otherwise, where do we stop adding new ones? After we have 6 of these
    (which is after this one). After 12? After the 20th?
