In Coreutils lib/ directory I found rand-isaac.c, which uses getpid() for
entropy, which is used by randread.c, which is used by sort(1) and shred(1).
rand-isaac is based on rc4.
I briefly checked into how it's used for shred(1). shred(1) will try to
use /dev/urandom first, and drop to rand-isaac after.
This looks like another good place to use /dev/erandom and arc4random(3).
