I can tell from experience that the Linux implementation of ASLR however is completely worthless. Why? Because the executable you launch itself isn't randomized. The executable must be completely trivial for there to not be enough usable gadgets to defeat ASLR. The Windows implementation is actually better in this regard since executables are randomized as well as libraries. However the randomization is the same for all processes and only changed on boot (because libraries on Windows usually uses relocations rather than PIC so the pages wouldn't be shareable if they were randomized per process), so an infoleak in one process can be used to attack another.
