>   Description     : hardened memory allocator
> This is a security-focused general purpose memory allocator providing
> the malloc API along with various extensions. It provides substantial
> hardening against heap corruption vulnerabilities. The security-focused
> design also leads to much less metadata overhead and memory waste from
> fragmentation than a more traditional allocator design. It aims to
> provide decent overall performance with a focus on long-term performance
> and memory usage rather than allocator micro-benchmarks. It offers
> scalability via a configurable number of entirely independently arenas,
> with the internal locking within arenas further divided up per size
> class. It can be added as a preloaded library using /etc/ld.so.preload.
