    I'm with Al on this. 50 Mb for decompression?
    Embedded and small device folks will not love this, I'm sure.
    *Maybe* we can use lzma. Seems to use 8Mb on decompression:

    30474 10708 8604 8760 392 8360 0 8 lzmacat pld-th-x86_64.tar.lzma

    (pld-th-x86_64.tar.lzma is a random 40Mb .lzma file I found on the net)

    Sizes in Kb again:

    32392 linux-
    33520 linux-

    P.S. sorting files by extension in tarball generally helps, but in case
    of Linux kernel, they are all C code anyway, so no measurable gain there.
