Sometimes (maybe ~1% ?!) in my CI report this error for no reason.

It's a large tools-deps cli project with many local/git/maven dependencies running on CircleCI/Docker

This is already logged as https://clojure.atlassian.net/browse/TDEPS-153, have some ideas on how to fix but have not had time to work on it yet.

I suspect that if you pass -Sthreads 1 that might work around it (I guess either way, would be good to know if it does).
