Async Rust with Tokio I/O Streams: Backpressure, Concurrency, and Ergonomics

I just published a blog post about async I/O in Tokio — covering how backpressure, concurrency, and I/O loops interact under the hood.

If you’ve ever wondered why `select!` might block reads, or how to design ergonomic async streams in Rust, this might resonate.

Would love to hear feedback, alternative patterns, or war stories from folks building async systems.
