Zig’s Io.Threaded is Neat
Summary
The post introduces Zig's Io.Threaded, a concurrency-friendly I/O interface that uses blocking syscalls with cancelation support. It clarifies the difference between concurrency and parallelism and explains Zig's signals-based cancelation protocol, including cross-platform nuances (POSIX signals vs Windows NT). The piece also critiques traditional thread cancellation and argues for a pool-based, cancelable threading model that separates concurrent vs async behavior.
