DNSSEC?

But it doesn't really matter if you zero out freed memory. Maybe it'll
prevent you from gaining some stale session info and the like. But even if
that were the case, this would still be a serious bug - you're not going to
reread your private key before encrypting each bit of data after all -
that'd just be wasteful.

In other words, this is kind of moot.
