`nerdctl commit` is not synchronous? (w/ kube)

[AkihiroSuda]

Thanks, but this seems to be a bug of nerdctl commit? It should be just synchronous?

Commit is definitely synchronous in a basic setup - but somehow not with kind+kube.

I do not know in enough details how kube would work on that ^.
Do you believe it could explain our issue?

The alternative explanation would be that commit is failing silently (in that case we will still see the failure if this patch does not address the issue)
