test result: FAILED. 22 passed; 10 failed; 0 ignored; 0 measured

Looks like either these files are being read/written concurrently or we've got stale artifacts from previous builds.

The incremental code should probably use OpenOptions::create_new instead of just File::create, but I still see no reason it could actually cause problems the way it is right now.
Each builder runs in its own directory, right? They each have their own tmp and the incremental code removes a file before trying to write it.

Hang on, the problem is that it's trying to load the dep graph at all, which was written by a previous build run? Shouldn't we just nuke tmp before each build?

I believe this was fixed by #33130 in 3001626, so the spurious failures have at least been fixed for now, so closing.

There is a FIXME related to this issue,
https://github.com/rust-lang/rust/blob/master/src/tools/compiletest/src/main.rs#L302
Now that the issue is closed can the FIXME be fix, or made more specific?
