Oh!  I think I might have figured it out, it's not actually the internal
behavior - it's the reporting of the address space.  In virtual_get_system_info
it sets the HighestUserAddress to user_space_limit-1.  My guess is that because
we're reporting back an address over the 32-bit limit (in my case 0xffff0000)
that Warden starts attempting to look in addresses that it doesn't have the
ability to check.  Using the following instead allows it to work:
info->HighestUserAddress = (char*)min((char *)user_space_limit, 0xc0000000)-1;

(note: 0x7fff0000 also works, but I'm not sure which is more appropriate - this
isn't really my area of expertise)
