    Booting Linux-2.4.22 with mem=16M, I can still compile the
    kernel as `make -j 16 bzImage` with the following resources:

    total: used: free: shared: buffers: cached:
    Mem: 14544896 14118912 425984 0 274432 6713344
    Swap: 1069268992 16510976 1052758016
    MemTotal: 14204 kB
    MemFree: 416 kB
    MemShared: 0 kB
    Buffers: 268 kB
    Cached: 3264 kB
    SwapCached: 3320 kB
    Active: 5980 kB
    Inactive: 2944 kB
    HighTotal: 0 kB
    HighFree: 0 kB
    LowTotal: 14204 kB
    LowFree: 388 kB
    SwapTotal: 1044208 kB
    SwapFree: 1028084 kB

    After a `make clean`, this configuration normally takes
    about 3 minutes to compile. With mem=16M, it takes about
    12 minutes. Not too bad.

    The kernel is as 'modular' as one can make it. I don't have
    any built-in stuff that I don't use. This helps keep it
    small. is growing in size for no obvious gain.

    -rwxr-xr-x 1 root root 1567340 Oct 14 09:39 vmlinux
    ^^^^^^^___ linux-2.4.22
    Both of these kernels have the exact configuration and are
    built with the exact same tools.
