Note about secure_zero
o There's now support to block mapping hashtables from being shrunk on map_delete().
o guaranteed_memset() is replaced with secure_zero() which fills a
buffer with zero. On x86 SSE2 is used to zero the memory without
loading it into the CPU cache, as this function is typically used
before calling free() on memory with cryptographic key data.
