status report:

async-experiments branch exists
it has a zigdig-async executable to try things out
it has poll() working
it hits a compile segfault just as i was getting to the deserialization part

reproduction steps

git clone https://github.com/lun-4/zigdig.git
cd zigdig
git checkout async-experiments
zig build install --prefix ~/.local/ --verbose

# if all worked,
zigdig-async

thanks to https://github.com/ziglang/zig/commit/43bffbb60878c9d6533532b23e29547d9f0f75be the compiler segfault became a compile error, though, even using the pattern described in the safe recursion issue, the compile error stays the same

maybe i'm doing something wrong with try await frame;, even though the frame lives on the heap, https://github.com/lun-4/zigdig/commit/5dee3c9b367a8fa8cb26fce787db09887fa7e53d
