Very interesting work.<p>Flate2 is an odd crate so I'm not too surprised to hear there's issues with it.<p>It seems unusual to rely on an FFI for something that isn't extremely intricate, broad, or brittle like syscalls / drivers / runtimes, I'd think that one zlib implementation would be as good as another, but maybe I'm naive.<p>Thankfully crates makes it pretty plain who would see fit to build on top of that.
