Unsure of the root cause, although rust-lang/cargo#6720 looks like a likely candidate.

Yea, I think I have a fix. Testing with docker is a little slow.

That can be an understatement. I tend to do some heavy editing of https://github.com/integer32llc/rust-playground/blob/master/compiler/base/Cargo.toml to reduce the number of crates that are required. It also looks like the intra-stage caching is broken again, at least on Travis, so that's probably not helping either.

I see #6734 has been merged, but the nightly playground is still timing out.
Is there another issue in play here?

[shepmaster]

I see #6734 has been merged,

There are multiple steps:

1. The fix has to be merged into the Cargo codebase (that was Fingerprint build script deps only for path packages. cargo#6734)
2. The Cargo update needs to be merged into Rust (this is Update cargo rust#59143)
3. Rust needs to be released (should be the next night, assuming nothing prevents the build from succeeding)

Thank you, @ehuss!
