Did Zig Fix Async / Await?

Zig is introducing a new async/await implementation that treats IO as an interface, similar to how allocators work in the language. This approach allows developers to choose their async execution strategy (thread pools, event loops, etc.) while writing the same code. The implementation leverages Zig's single compilation unit strategy and explicit memory management to provide better resource control, testing capabilities, and cross-platform compatibility. The new system enables features like cancellation and select operations in userland, though it will require significant breaking changes to existing IO code.
