On this one I took a similar approach but chose to extend =E2=80=98spawn-command=E2=80=99 instead of introducing a new procedure=E2= =80=94see commit 0f3276a9c3dafbef41b0aab88ba5dda1bb78dc99. Another difference is explicitly listing keyword arguments so that their default values are taken from the caller=E2=80=99s dynamic state and not fr= om that of the process monitoring fiber. This fixes . Let me know what you think! Thanks, Ludo=E2=80=99.
