If you genuinely worry about address space related exploits, you will know that ASLR is not really going to save the day regardless of the RNG used, although obviously some randomization is needed.

Random numbers for ASLR

ASLR can make attacks very much harder, but only on 64-bit systems (and of
course only if more than 8 bits of randomness is used). On 32-bit there
isn't the room to make attacks significantly harder :(
