Very good catch!

Ensuring there's only one backport operation running at once, surely sounds like a good idea to me.

I also notice that script needs some love related to logging, primarily replacing debug with JSON logs via bunyan (read: options.logger) so that we can get a hold of those logs from anywhere / anytime.

@Trott just to confirm; is this functionality still valuable? I haven't been involved in core for a while, but I do remember disabling the dont-land-on-* labels in acd5bc1#diff-eea09a4f0f8288ff9bd49ef44625f0c1. Should we keep it (and improve it) or delete the whole script?

I actually have no idea. Is that a question for @nodejs/build or @nodejs/releasers or someone else? /ping @nodejs/github-bot while I'm at it I guess.
