Sheer luck: the first call to VirtualAlloc succeeds because it asks
for an amount that is much smaller than the 64-bit address space.

It worked for me in 32 bits for the same reason.

The problem only rears its ugly head when the first call to
VirtualAlloc fails.  Then we need more iterations, which don't happen.
