    This is a good idea. However, I might suggest using gcc 4.0 (you'll
    have to use a snapshot now, but the release should only be a few weeks
    away). A patch went into gcc 4.0 that makes gcc more intelligent
    about sharing stack for variables that cannot be alive at the same
    time, and therefore it may be more feasible to make unit-at-a-time
    work for the i386 kernels.
