A core component of Crystal’s concurrency model is the event loop. It integrates asynchronous operations into the runtime, enabling other fibers to run while one fiber waits to read data on a socket, for example.

We’re changing how the event loop operates under the hood on Unix systems in #14996.

The new implementation integrates the Crystal event loop directly with system selectors, epoll (Linux, Android) and kqueue (BSDs, macOS) instead of going through libevent.

We’re removing an external dependency an...
