2017-09-08Fix one-second spin in fx_random.cppTom Sepez
Take seed generation logic from base's address_space_randomization.cc. One small tweak is to avoid the bottom three bits of a stack address and invert, to make leaking ASLR more difficult along the lines of the freelist masking in base's partition allocator. Another tweak is to mix in some more time-based information. Another tweak is to add in the times called so that rapid successive calls return different results.
