Could be. Does Microsoft publish any documentation about the range of
addresses their ASLR uses?
Obviously, any such fix would be a lot more likely to be reliable in
64-bit machines. There's probably not enough daylight to be sure of
making it work in 32-bit Windows, so I suspect we'd need some retry
logic anyway for that case.
