Is this...okay? Like, from what I can tell, it should be,
since s1 and s2 are restricted. s1 and s2 shouldn't be the
same object. But, like, I'm worried about what happens if
someone passes in the same pointer for s1 and s2. You'd get
an infinite loop of adding stuff that just eats up all
memory from there! But, like, I think musl does the same
thing? I really can't tell. For now, I'm gonna assume I've
done this acceptably.
For now.

I'm pretty sure musl does the same thing, for the most part.

Does weird stuff. Maybe don't use until we figure out what
