There is no reason why the loop to clean up any pending signals should need more than two iterations to complete any SIGALRM and SIGCHLD remaining. Break the loop after 5 iterations and abort if it ever take this long, and sleep for one second every iteration to give even slow machines time to process the child. On GNU Hurd, the loop some times got stuck (around 1/3 of runs during my testing) in a endless stream of SIGCHLD signals. This code change ensure the test exits with an error instead of getting stuck forever.
