NOTE: This step skips DLLs which loaded at their preferred
address in the parent because they should behave (we already
verified that their preferred address in the child is
available). However, this may fail on a Vista/Win7 machine with
ASLR active, because the ASLR base address will usually not equal
the preferred base recorded in the dll. In this case, we should
make the LoadLibraryExW call unconditional.
