Log Message:
correct performance regression of recent change from select() to
poll() for parallel make:
 - Make the poll() code behave more like the select() code: sleep for
a bit waiting for output rather than busy-wait (eww).
 - Install a no-op SIGCHLD handler so that poll/select wake up early
(with -1/EINTR) when a child exits.
 - Change the default sleep time from 500ms to 5 seconds since we now
wake up promptly when a child exits.
