`MessageStream` unfavourable interactions with `tokio`'s co-operative scheduling about rust-rdkafka

Another option is to add some code for detecting when a task is voluntarily yielding, like FuturesUnordered does.

I agree consume_budget would be ideal, but it's not cross-runtime. There's a proposal to address that, but I don't know if it has any traction.

Given it was closed early-mid last year, I don't think there is much traction.

I've been thinking about the approach, and I wonder if you'd be open to having a solution toggled by the tokio feature. Then if this is also noticed with other executors, if any of them are following a similar approach to co-operative scheduling their solutions could go under their own features.

I realise it's less than ideal, but would solve the problem in the short run and would hopefully be an easy lift if something like consume_budget is standardised in the future.
