Workflow runs flaky / "Text file busy"

In both the workflow runs
- (#320) https://github.com/effekt-lang/effekt/actions/runs/7034447758/job/19142525276?pr=321 | https://github.com/effekt-lang/effekt/actions/runs/7034447758/job/19142525276?pr=321#step:9:208
- (#321) https://github.com/effekt-lang/effekt/actions/runs/7019874175/job/19098324052 | https://github.com/effekt-lang/effekt/actions/runs/7019874175/job/19098324052#step:9:197
one of the tests fails with something like
```
==> X effekt.ChezScheme*Tests.examples/pos/multieffects.effekt (chez-callcc) 2.115s java.io.IOException: Cannot run program "*": error=26, Text file busy
```

This is probably a chance event, and might be related to https://bugs.openjdk.org/browse/JDK-8068370.
Leaving this here because it occured in both of my last PRs, so we might want to look into this if this stays this frequent for more than two runs.
