The goroutineleak Profile in Go 1.26 — Catching Goroutine Leaks with GC Marking
Go 1.26 (released February 10, 2026) added a goroutineleak profile to runtime/pprof as an experimental feature. The idea is to recycle the GC's marking phase — mark using only runnable goroutines as roots, then report as
