If the docs say 256, I'd suggest using that not just for stable, but
for anything. Maybe 511 bytes work everywhere and the docs are just
wrong. And maybe it doesn't. I'd rather start out conservative, and if
somebody can show that it really matters, and that 511 bytes really is
always safe, we can do it then. But I don't imagine that the
difference between "chunk it up to max 511 bytes" is really noticeably
faster than "chunk it up to 256 bytes max".
