     = note: consider calling `.wait()`
     = note: not doing so might leave behind zombie processes
     = note: see https://doc.rust-lang.org/stable/std/process/struct.Child.html#warning
     = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#zombie_processes
     = note: `#[warn(clippy::zombie_processes)]` on by default

The API caller should ensure that they call .wait() or equivalent on the
spawned child to reap it.
