+background process to finish; get the exit status of finished processes; kill
+background processes and their children; restart processes.  It can read the
+standard output and error of the processes, using non-blocking connections.
address@hidden can poll a process for standard output or error, with a
+timeout.  It can also poll several processes at once.")
