We observed non-deterministic test failures in one of our switch tests,
which would happen if the GC would run between iterations of the accept
loop. As we don't hold any reference to the connection the setup
finalizer might get triggered and therefore the file handle closed. For
the curious check the references on finalizers and the variable scoping
in the spec:

To achieve faster feedback cycles for our feature PRs this change
reduces the average buildtime from 35 to ~6min by utilising their new
2.0 offering based on docker and nomad. We make use of parallel build
steps wherever possible so that the duration is determined by the
slowest test suite (p2p).

This is an intermediate step until we move our CI/CD completely
on-premise for more control and added security.
