Go 1.22 added contention on runtime-internal locks to the [`mutex`
profile](/pkg/runtime/pprof#Profile). Contention on these locks is always
reported at `runtime._LostContendedRuntimeLock`. Complete stack traces of
runtime locks can be enabled with the [`runtimecontentionstacks`
setting](/pkg/runtime#hdr-Environment_Variable). These stack traces have

      <a href="/pkg/sync#Mutex"><code>sync.Mutex</code></a> and
      <a href="/pkg/sync#RWMutex"><code>sync.RWMutex</code></a>.
      Contention on runtime-internal locks is always reported at <code>runtime._LostContendedRuntimeLock</code>.
      A future release will add complete stack traces in these cases.
