ocess completes. Returns the subprocess return code. os/proc-wait cannot be called twice on the same process. If `ev/with-deadline` cancels `os/proc-wait` with an error or os/proc-wait is cancelled with any error caused by anything else, os/proc-wait still finishes in the background. Only after os/proc-wait finishes, a process is cleaned up by the operating system. Thus, a process becomes a zombie process if os/proc-wait is not called.</pre><a href="https://janetdocs.org/os/proc-wait">Community Examples</a>
