That is totally fine with me.  May I ask why we might pursue supporting
32-on-64 plans?  It would certainly push us to have portable RPC
declarations.  I personally only want to run a 32-bit or 64-bit OS and
not a combination.  Can you help me see the value in a 32 bit userland
on top of a 64 bit kernel? Just curious.
