Another example is the various frameworks that provide the TextEdit boxes where passwords are entered. FIPS requires zeroization at level 1, and I guarantee none of those frameworks wipe the memory from the TextEdit. Hell, Apple has a secure allocator that does not even bother calling the secure deleter. It calls the default deleter for some reason. See the source code for libsecurity_utilities at [1,2,3]. And Apple really could have used zeroization: http://www.cnet.com/news/mac-os-x-lion-reveals-passwords-in-sleep-mode/. As this vulnerability shows, wiping secrets from memory is not a theoretical defense.
