"could not create control compt"

I'm on Win-10 and seems to have built Unbound and the Pytho3 module OK.
Test outputs from:

* `libunbound/python/examples/async-lookup.py:` Resolve error: could not fork
 * `libunbound/python/examples/ns-lookup.py`: Result:
      raw data: 05 70 69 70 69 74 03 63 69 73 05 76 75 74 62 72 02 63 7A 00;05 72 68 69 6E 6F 03 63 69 73 05 76 75 74 62 72 02 63 7A 00

Seems pretty okay to me.  But using an Python3 adaption of `ubmodule-tst.py`, shows these errors:
```

```

I did cook up an `run/example.conf` based on ` doc/example.conf.in` containing:
```
server:
  module-config: "python validator iterator"
  python-script: "F:/MinGW32/src/inet/DNS/Unbound/run/ubmodule-tst.py"
```

What is this `"control compt"` an how can I fix this?

**System:**
 - Unbound version: 1.18.1
 - OS: Win-10
 - `unbound -V` output:
```
Version 1.18.1

Configure line: --with-libexpat --with-openssl --with-pyunbound --with-pythonmodule
[warn] signal.c: socketpair: Programmet har ikke kalt WSAStartup, eller WSAStartup mislyktes.
Linked libs: event winsock (it uses WSAWaitForMultipleEvents), OpenSSL 3.2.0-alpha3-dev
Linked modules: dns64 python cachedb respip validator iterator

The `[warn] signal.c:` seems unimportant for this issue (`WSAStartup()` was not called).
