This reverts commit f2648b2. While the idea to never use swap was fine, in practice this meant that when nix ran OOM, some other process was killed instead. This lead to the job not being possible to be cancelled anymore and thus needing to timeout, before subsequent jobs could be scheduled. This can take up to 6 hours for GitHub Actions by default. Re-enabling the swap file to catch this case more gracefully. It's still the goal to never actually *use* the swap file during Eval and just a safeguard. Keeping the changed chunkSize and not reverting it - this makes it slightly less likely to hit the swap file when running with Lix. (cherry picked from commit 9cde368)
None of our jobs is expected to run for 6 hours, the GitHub limit. These limits are generous and take into accounts that some jobs need to wait for others. If jobs exceed these times, most likely something else is wrong and needs investigation. (cherry picked from commit 436d541)
