And, if > so, then how? A zombie is a process which has terminated but hasn't been wait()ed on (aka "reaped") by its parent. Most libraries which create child processes make some effort to reap them. E.g. the subprocess module keeps a list of "orphaned" processes (those for which the Popen object was deleted while the underlying process was still alive), and polls the list periodically (specifically, whenever a new Popen object is created).
