You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: orphan.rs
    path of file: ./repos/tokio/tokio/src/process/unix
    
    the code of the file until where you have to start completion: use crate::loom::sync::{Mutex, MutexGuard};
use crate::runtime::signal::Handle as SignalHandle;
use crate::signal::unix::{signal_with_handle, SignalKind};
use crate::sync::watch;
use std::io;
use std::process::ExitStatus;

/// An interface for waiting on a process to exit.
pub(crate) trait Wait {
    /// Get the id
    
    fn no_reap_if_signal_lock_held() {
        let handle = SignalHandle::default();

        let orphanage = OrphanQueueImpl::new();
        let signal_guard = orphanage.sigchild.lock();

        let orphan = MockWait::new(2);
        let waits = orphan.total_waits.clone();
        orphanage.push_orphan(orphan);

        orphanage.reap_orphans(&handle);
        assert_eq!(waits.get(), 0);

        drop(signal_guard);
    }
