There was a problem hiding this comment.
Found a minor typo and am interested in trying to learn a little more about rust if you have the time to answer some questions :-) Also, I don't see any notes in CONTRIBUTING.md about reviewing PRs so I hope I'm not out of line in reviewing this. If there are some docs regarding when/how to review PRs - please link me to them so I don't make the mistake again.

…iser Fix race condition when allocating source files in SourceMap This makes allocating address space in the source map an atomic operation. `rustc` does not currently do this in parallel, so this bug can't trigger, but parsing files in parallel could trigger it, and that is something we want to do. Fixes rust-lang#69261. r? @wesleywiser
