spawn_with_attributes for Command on

[heaths]

Is your feature request related to a problem? Please describe.

To have a process write to a pseudoterminal (pty) on Windows, you need to adjust its thread proc attributes. There's currently no way to do this with tokio::process::Command.

Describe the solution you'd like

It would be great if tokio added support on Windows like the nightly CommandExt::spawn_with_attributes. I'd be happy to submit a PR.

Describe alternatives you've considered

I'm using std currently and reading in a spawned task not only is this the only place I'm using std::process::Command instead of tokio's, but without all your async plumbing I'm having trouble waiting for a BufReader to finish after the process terminates. This already works correctly with tokio.

There is currently no mechanism to let Tokio to access unstable features in std. Not even --cfg tokio_unstable allows that. We cannot support this at this time.
