When I remove the "inline" option the build + test time becomes <10 seconds. So
the weirdly slow part is related to inlining.

and:

```
DMD 2.077.1 for linux32: 3 min 20 sec
DMD 2.077.1 for linux64: 3 min 16 sec
DMD 2.077.1 for mac64: 5 min 4 sec

DMD 2.078.0-rc.1 for linux32: 13 min 30 sec
DMD 2.078.0-rc.1 for linux64: 9 min 39 sec
DMD 2.078.0-rc.1 for mac64: 10 min 56 sec, then the job was aborted
```
