So, does /Zm800 hurt?

Yes, it can.  We reserve address space based on that value, and that
means we can reserve much more than we need (in this case, on a 32 bit
machine, we'd reserve an extra 350 MB of memory.)

Sometimes this switch causes odd problems with a pch.  It could also
hurt throughput.
