Log message:
Ok, there was a need for OPENSSL_cleanse() instead of bzero() to prevent
supposedly smart compilers from optimizing memory cleanups away. Understood.
Ok, in case of an hypothetically super smart compiler, OPENSSL_cleanse() had
to be convoluted enough for the compiler not to recognize that this was
actually bzero() in disguise. Understood.
But then why there had been optimized assembler versions of OPENSSL_cleanse()
is beyond me. Did someone not trust the C obfuscation?
