scudo requires 64-bit atomics which make libc hookup on 32-bit systems a bit of a pain but nothing that cannot be overcome

it can only use the primary32 allocator on 32-bit systems, which is fine, chimera uses primary32 universally because it uses less virtual memory while performing more or less the same in practice

it's significantly and visibly faster than mallocng in most things user-facing, effectively anything that allocates and is multi-threaded (e.g. builds - LTO linking times take a third the time, web browsers are snappier, java is snappier, etc)
