If you have time for a quick review @obaudys, I'd be grateful.

Looks good to me; it neatly spells out what is going on and why.

You seem to have closed the impl block and then reopened it:

}

impl Process {

Is there any reason for that? Asking as a rust newbie.

It's subtle, but I added some docs to the impl block on line 779. This isn't all that well known (and honestly not used that often), but you can add documentation to the impl block itself, as in:

/// This is some docs
impl Foo {
    /// Create a new thing
    pub fn new() -> Self { todo!() }
}
