Hardened Malloc - Hardened Memory Allocator

It can be useful for SecBrowser and even Tor on the GW if we test for breakage. Perhaps assigned for bash instances if it detects it is installed. While we can’t/shouldn’t switch the entire system to it we can do this on a per process basis.

That sounds like a good idea although how would we get programs to use it by default? Would it need a bunch of wrappers?
