Maybe?  That seems like it would be fairly reasonable, but knowing
what the overhead numbers are would help.  To be clear, right now we
have things set thusly for NR_CPUS:

arm=8
ppc32=4
ppc64/ppc64p7=1024
s390x=64
i686=32
x86_64=128

I believe our specific discussion here is about x86_64.  I don't think
we're going to change i686 to anything higher than what it's set at
right now.
