Yes, that seems to be due to a flaky test. I believe it is related to #5207. on |

Motivation
For inter-process communication over stdin and stdout it would be helpful to use vectored writes.
Solution
Expose already existing vectored facilities in
tokio::io::PollEventedon theAsyncWriteimplementation oftokio::process::ChildStdinby providing a forwarding implementation instead of using the default non-vectoring implementation.Adjusts the
tokio::io::PollEventedvectored writes support to be enabled onfeature = "process".
