[erlang-questions] simple_one_for_one supervisor, transient restart strategy

[Paul Peregud]

I've distilled the code to minimal form. And the error is no longer
there. So it seems that I misdiagnosed the source of the problem.
Anyway - here is the code:

When I send the messages stopnormal or stopshutdown, the child dies without getting restarted. When I send a stopabort, it gets restarted with the arguments with which it was created.
