These constructors have been const since Rust 1.63 (rust-lang/rust#93740). It's pretty easy for us to make them const too, which allows code that relies on them being const to correctly compile with Shuttle. The one exception is that HashMap::new isn't const, and our Condvar implementation uses a HashMap to track waiters. I took the easy way out and just used a vector as an association list instead -- we shouldn't expect large numbers of waiters on the same condvar, so this shouldn't be too inefficient.
