 Rust CI ensures that the master branch of rust-lang/rust is always in a valid state.
 
 A developer submitting a pull request to rust-lang/rust, experiences the following:
-* A small subset of tests and checks are run on each commit to catch common errors.
-* When the PR is ready and approved, the "bors" tool enqueues a full CI run.
-* The full run is either performed or the PR is "rolled up" with other changes.
-* Eventually a CI run containing the changes from the PR is performed and either passes or fails with an error the developer must address.

 The large CI run times and requirement for a large builder pool is worth it because it:

-* allows bisection when bugs are discover later
