[issue1924] mmap - add mmap offset randomisation

Alex Hornung <[e-mail]> added the comment:

Well, karc4random calls arc4_randomstir(), which calls read_random_unlimited(), 
so it *is* using the same entropy as /dev/random and /dev/urandom.

I'm not sure I understand your point considering the above. I don't think 
reading directly from read_random_unlimited() on each and every karc4random() 
call is a good idea at all. This way it gets called every few times, it seems, 
which should be good enough (?)

Cheers,
Alex
