    Arjan, I've been doing some work on traps_32.c porting over the
    oops_begin()/oops_end()/_die() arrangement from traps_64.c and
    then use it in unifying some more parts of fault.c.

    If you have other work in this area, I'll hold off until your stuff
    goes in...feel free to send me any work in progress stuff and I can
    try to coordinate with you.

    Harvey
