Hi. I've tried to add your case to the repository and at it seems 
to be working for me.
At least with dmd-2.085.0.

When run with `make dynamicd`:

```
main shared static this
+main()
utils shared static this
worker shared static this
libworker.so is loaded
entry_point1() function is found
entry_point2() function is found
...
-main()
unloading libworker.so
worker shared static ~this
utils shared static ~this
main shared static ~this
```
