Follow-up for bug 946208. I have just disabled rust-onig on arm64 as we
were having several workers down. I inspected one of them and it had this:

Also, looking at the history, it hardly ever succeeds (only
ci-worker-arm64-01 seems to have enough disk space):
https://ci.debian.net/packages/r/rust-onig/testing/arm64/
and wasting a lot of resources that way.
