AI-generatedSignal-based preemption latency in tight-loop goroutines
Since Go 1.14, the runtime utilizes asynchronous preemption via OS signals to interrupt goroutines that exceed their time slice. While this prevents tight loops without function calls from starving the scheduler, high‑concurrency environments on many‑core systems frequently exhibit unpredictable tail latency spikes. When many goroutines are executing CPU‑bou
