If I may suggest, rather than blocking the sender in case the channel is full, I suggest simply returning an error (or raising a condition) immediately.
This is both extremely simple (for the channel implementer) and heavily customizable (for the user). It seems certainly much easier than provide an extremely wide array of different channels as part of the core Rust distribution... and actually makes it possible to build libraries for common cases (such as local queuing). -- Matthieu.
