Looks like that conformance-using-vfs job really is I/O bound. |

Would it be better to assert errors immediately in the go routine?

Sure. They're safe to be called outside of the goroutine that's running the test (their require counterparts, not so much).

And they both are in the new setup, the conformance test jobs don't complete within the timeout when they currently finish on main. |
In cases where we _prefetch an image, don't create a working container using "--pull" if we only care about the ID of the new container, i.e., we don't care that we actually tried to pull the image from the registry. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>
The buildah_version and buildah_info tasks run the main binary without making sure that it's been built first. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>

Parallelize (most of) the subtests in TestConformance() and TestCommit(). Use t.Cleanup() instead of "defer" for a few cleanups. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>

What type of PR is this?
/kind failing-test
What this PR does / why we need it:
Parallelize more subtests to try to finish conformance testing faster.
Use t.Cleanup() instead of defer for a few cleanups.
How to verify it
Conformance tests should complete in less time unless they're I/O bound.
Which issue(s) this PR fixes:
Special notes for your reviewer:
The "conformance tests using VFS" job seems to be limited by I/O, as it's not faster when given more memory and more CPU, and actually appears to be slower when we add the parallelization here. The overlay counterpart, however, finishes in less time than it did before.
Does this PR introduce a user-facing change?
