test-skeleton: Kill any child process's offspring
This makes sure any subprocesses created by the program being tested get killed as well if their parent times out. Otherwise if they are really stuck, they may remain there running forever after the test case and then the whole test suite has completed, until killed by hand. * test-skeleton.c (signal_handler): Kill the whole process group before killing the child individually. (main): Report any failure on `setpgid'.
