`pollster` in the stdlib would probably make sense. But of course there's nothing stopping anyone from using the `pollster` crate today.

Pollster in the standard library provides several major benefits outside of just using it yourself.

- it provides an incentive for libraries to be pollster compatible, rather than requiring tokio. And pollster compatible means executor agnostic.

- libraries would document their library with pollster usage
