Skip stale fiber durations to prevent profiler ranked-chart crashes

Skip stale fiber durations to prevent profiler ranked-chart crashes targets a $40.0B = 25M professional developers x $1,600/year average spend on developer tooling, observability & performance tooling total addressable market with medium saturation and a year-over-year growth rate of 12-18% -- driven by rising investment in observability and frontend performance.

Key trends driving demand: Framework complexity -- concurrency and fibers increase transient states and profiling edge-cases, boosting demand for robust profilers; Observability consolidation -- dev teams expect unified traces, metrics, and frontend profiling in one platform; AI-assisted debugging -- machine learning can correlate traces and suggest root causes from noisy profiling data; Shift-left performance -- teams profiling earlier in CI/CD pipelines increases need for non-flaky, deterministic tooling.
